Mileseey S50

I don’t usually give a damn about laser measuring gadgets. The only one I’ve ever owned was some cheap Bosch “Blaze” I grabbed for fifty bucks. It was fine for rough numbers… good enough to measure a closet, not good enough to trust when cutting lumber for built-ins. A toy, really.

Then Mileseey threw me a curveball: the new S50. Supposedly a hotshot accuracy monster with a green laser bright enough to blind a squirrel, four reference points, dead-on within a sixteenth at 400 feet, slick IPS screen, and a battery system so clever you can run it on AAs or the USB-C rechargeables it ships with. Fantastic marketing fluff.

But goddamn… IT WORKS. First test was my office alcove where I wanted a desk. Tape said about 3’ 9 and 31/32”. The S50 said the exact same thing. Not close. Exact.

Next, I needed the length of a roof section on my lab for a gutter. Normally that’s a two-man, two-ladder circus. With the S50? Set the laser on one point, push a button, aim it at the other point, push again and… BOOM. Spits out a distance within a sixteenth. No sweat, no cussing, and no ladders needed.

And if you’re hopping around measuring ten different things, don’t worry about losing the numbers. This little bastard syncs to your phone, logs them all, and even lets you label each one.

I’m sure this thing has a hundred other tricks buried in its guts, but I’ll never know. I’m no power user and that’s actually the beauty of it. The S50 is stupid easy to run. I never cracked the manual, just mashed buttons until it all clicked, and five minutes later I was measuring like I’d been born with the damned thing in my hand. Intuitive, fast, no bullshit.

I mean, I rarely get excited about free swag from tool companies. Usually it’s junk that ends up in the Goodwill pile. But the Mileseey S50? This one’s different. It’s black magic in your pocket, and for $140 it’s pretty cheap sorcery… Hell if I know what the laser-measuring market looks like, but this one feels worth every dime.

Anyway, details here.

I have the same cheap Bosch, it works OK.

I've never seen the real need for something better. Maybe I'm missing something.

One tool that I use all the time is a cheap 3 plane laser level. I measure the level/height of floors - see if stuff is vertical and horizontal all the time.

I have a few and one of the more expensive Bosch lasers that I use all the time. I use it for measuring rooms all the time to get sq footage for flooring, or wall sq ft for paint or linear ft for trim. Don't need exact for that, just close. But I have also used it for installing trim, especially crown moulding and the accuracy comes in handy for that. For the most part I can measure the wall and cut and it's pretty accurate. I would argue almost more accurate then trying to hold a tape measure from corner to corner while up on a ladder.

For me, the eye opener was measuring for a gutter... located 14' up... from the ground. I don't even pretend to know how it's so accurate doing something like that. But, it's repeatable.

To me, it was just another tricky toy before it pulled that off. But that opened my eyes to other things... The desk I mentioned for instance. Now that I trust its results, I just quickly measure the dimensions of the space and store those measurements in my phone. So, when I get back to my bench I can sit down with my phone and my Shop notebook to draw up plans. Convenient as hell.

But also, just simple ****. It's hard to measure accurately between two walls where your tape gets captured. Not with this thing.

Does everyone NEED one? Probably not... But I sure like it... and I really didn't want to. Hell, the only reason I paid any attention to it at all in the first place was that I got an early copy and I felt obligated to at least give it a shot. Glad I did.

they are great for things like estimating flooring, paint, a real estate listing, etc. That doesn't require much precision, and so lots of them ****. But an accurate one is good for all sorts of jobs around a construction site. need to measure the height required for a post? Distance for a ridge beam? Easy to do with one person, no messing with ladders. The data logging on fancy ones gets used to import as-built measures into CAD.

Touchless measuring with accuracy will be an absolute game-changer.

I've seen similar gadgets used for estimating stuff like floors, paint, etc, of course, but I had no idea this kind of accuracy was even possible.

Of course, I have far more than $140 worth of tape measures scattered throughout my environs so that I can usually find one when I need it... and I don't even use tape measures that much.

So can I assume this one can also help the user find it? Does it holler when you say a key phrase like "Where's that &^%$#! measure?", or do you have to clap in a certain pattern, or use your phone, or something?

I noticed that it has a 1/4" thread in the base for tripod mounting and such. So you could mount it to a pole and take measurements without climbing a ladder. So the technology could also make life a bit safer.

I have an early version of a Mileseey unit, mine is a S2 which I bought back in March of 22. I have to be honest, I haven't used it much but do find it vary handy. With my mobility disability it is useful as I don't have to move back and forth when getting measurements for some things. None of these require the precision most of you are referring to but useful o me none the less.

It would be nice to hear how it performs under bright sun, and if the spot is clearly visible.

It's good if it works well. Maybe, at some point I'll have to replace my trusty Leica.

Looks good. If you have a chance to check it from a much longer distance, it would be perfect.
Thank you, Ryan.

I tested it from 44'3" and could still see the laser, but didn't have a way to photograph it. At some point, obviously, it becomes about eye sight...

it's more data privacy now that i have degoogled and field stripped the software out of my android. most apps are just to scan your phone and sell everything on it to data brokers. That why laser measuring devices and sump pumps use or require apps. even new cameras now must be activated over the internet or they will not turn on or brick\self destroy in 7 days. hence why i buy old cars and devices and collect to tools to fix and remodel such old things. yes i know you were razzing me. i'll try not to go full vegan on you guys too often :p

i did add this to my amazon cart to take a look at later, i have not bought measure laser yet just a dewalt level laser.


im thinking the laser would be baller for crawl space measurements if there is line of sight.

Tinfoil hat or not, I totally get this sentiment. Given the times we live in, I am very concerned about data privacy. In fact, I've gone so far as to use dummy accounts on dedicated machines using tools like Wireshark to monitor data tracking. After doing so and seeing the kind of data Facebook collects with my own eyes in real time, I was left in awe how such a thing could even be legal. It's gross... and if you use Facebook (or anything in the Meta-verse), it's probably too late for you - app or not. You are owned.

That being said, your statement on modern cameras is false. At least with brands like Nikon, Canon, Leica, Sony, etc... They aren't bricking cameras if you don't register them. And while I don't have experience with all of their accompanying apps, I can say that neither Nikon or Leica collects any inappropriate data through their phone apps or their cameras.

Chinese made drones (DJI) are a completely different story obviously...

But, I can also tell you that the app this laser measuring device uses sends no data back at all and can even be used offline.

Well, now it has a $40 off coupon on Amazon for a bit...
Dang it. Add this to the "Tools I didn't know I needed" list.

I love my Bosch GLM80 but after several years of use, it shows a 1/2 battery then turns off. I got a new 3rd party battery but the plastic clip was too soft and deformed when I tried to plug it in. I use it a lot so I grabbed a Bosch GLM100 to replace it while the other was down.

I usually do foundation measurements so it's easy to guess the total length if the Bosch is off a little but the little guy is highly accurate and it has a very bright dot. The GLM80 can measure up to 262' but it's impossible to see the dot over 50' in sunlight. I was curious about the accuracy after reading this so I just did simple measurements with fixed points and the GLM100 repeated them over and over. If the distance is smaller, say a deck or cabinet, I'll still verify with a story stick but the Bosch is nice for getting really close.

Mileseey has some interesting products on their website, the inferred is a fraction of the price of a Flir, I'd look them over if they ever show up in the local tool store, it's always good to have competition.

DJI makes action cameras now, also the gimbals. my DJI gimbal has to be online and registered with an email address to "activate". if i'm wrong i know at least brand of action camera is the same way as my DJI gimbal. ill probably use a google pixle flashed with Graphene OS to install their "software"


at least s50 can be used offline. wonder if it will have any black friday drops.

I'm pretty careful about stuff on my phone. I've never logged into Facebook - ever.

Still it gets me. I have a throwaway email account that I use for questionable communication. Yesterday a friend who does comedy was talking about setting up an event in Eventbrite - which I never heard of. I said "Event bright" or "Event light"? to her. I didn't even look it up. In the next three hours I get three emails from Eventbrite. I have no idea how that happened.

I hate that thing - I've begun not carrying it with me for hours at a time, which seems to drive people nuts when I don't answer their calls/texts/emails instantly.

So went to use my bosch GLM165-27cg yesterday and it's dead, lots of similar stories on bosch's website. Almost 200 bucks lasted a year roughly. Looking into this mileseey on sale for 99 bucks right not.

Does it do square footage of rooms? I didn't see it listed in the amazon description but may have missed it. Also will it do running totals for measuring how much trim you need for a house? Those are two things I use a lot for figuring out a bunch of stuff like how much trim to buy, how much paint to buy for walls and ceiling, how much flooring I need, etc. Anyone that has one can confirm it does these things? I'll order one if it does. Thanks

Edit: Looks like it will do sq footage but didn't see anything that says it will do a running lineal footage.

I've been very happy with my Mileseey G2. Mine is the 330' option, it looks like only the 200' version is available right now. Accuracy is right in line with the "name brand" units I've tested it against.


I've got an older, company issued Bosch (Blaze) GLM50C that I use a lot as well. It's okay, but the 165' range is severely limiting for what I do and I often bring my Mileseey in from home.

These are very good for commercial/industrial dimensions, but I find I would still need a tape measure for things the laser cannot check.
This one has worked well for me inside the home.
https://www.garagejournal.com/forum...thers-may-not-know-about.550120/post-11331346

If I want to measure the dimensions of an object, I use the tape measure.
Then I turn on the laser to confirm dimensions of the space.

I’m going to give this a go, they had it for $109 on the site and then a 10% of code (welcome10 I think). Even better they didn’t charge me tax like Amazon would have.

We use the Bosch lasers quite a bit at work to measure pipe sizes and elevations in inaccessible or confined spaces. I'm really curious to try out one of these Mileseey lasers.

Also on the data privacy bit, I can tell you that the Bosch units at least are allowed to enter military comms-restricted secured areas, as long as you go through the steps to get it cleared.

I ordered one of these after my expensive bosch stopped working, thanks for posting about them. I've been in construction pretty much my whole life and have used laser measurers for over 10 years now. Mostly just for getting measurements for estimates and ordering materials. Decided to tray using it instead of a tape measurer for a few projects and what a game changer. A few weeks ago I was putting up a bunch of crown molding and used it to get measurements to cut each board and it was really accurate and easy to do on 10-15 ft walls. Then last week I started redoing our finished basement. In the past I have anchored the bottom plate to concrete and then shoot laser up to install top plate. Then use tape to measure each stud. I used the milesey to get my measurements and each one fit perfect, as good if not better then using a tape. Also used it for getting sq ft of walls to know how much paint and the same for flooring. Then used the running total feature to get how much trim I needed. So far I'm really impressed with it, especially for the price. Thanks again for sharing about them.
