BOSCH GLM165-27CGL 165 Ft Blaze Green-Beam Laser Distance Measure with 3.7V Lithium-Ion 1.0 Ah Battery, Includes 1.0 Ah 3.7V Lithium-Ion Battery, Belt Clip, & Pouch

Whoa!!!!!! Serious tool. In 2025 i believe this is the minimum to spend for a laser measure that isnt a toy. Homeowner creating as built plans. I previously used a dewalt dw055pl which is a tiny $40 thing with nice color screen but no bluetooth, no tripod mount and no inclinometer. It was very difficult to point level and keep steady so measurements were not square and results were poor. Tried out the leica but screen is awful to read in crawlspaces and unit i wanted was >$150 more. Finally ordered this bosch because of the positive reviews and it claimed to have all the features i wanted. From description I was unsure what i was getting and am very pleasantly surprised. This GLM165-27CGL is a kit that comes with a soft case and a lithium battery, a charge cable, a tripod screw mount AND can still accept AA batteries. The non-‘L’ version is still available for the same price, but to be clear the ‘L’ version is the same but also includes the $30 lithium battery upgrade. The lithium battery plugs into the AA battery bay and replaces the back used with AA batteries. This is awesome because i can swap in AA batteries if the lithium battery loses its charge or gets old. I will be using the lithium battery until it has a problem, but that means i must store the AA battery back and not lose it. The device has nice rubber buttons that yield with satisfying dull click. The laser is bright green and very easy to see. There is a dedicated units button on the face so you can change quickly. When a reading is taken the device gives a quick buzz to affirm. Device is able to interpolate distance or height using the inclinometer. This allows double indirect height measurement meaning you take a reading at the base of a vertical wall, then a reading at the top of the wall and device will tell you the vertical distance between the points. More useful is that device has a mode to use inclination to give you horizontal distance even if you don't keep the tool flat. For example if you set it in Pythagoras distance mode you can point it at the base of a wall and it will give you the horizontal distance to the wall. This is convenient because it will still give you reasonably accurate readings even if you don't keep the device perfectly flat. What this device will not do is a true point-to-point measurement, meaning you cannot point it at two random spots on a house and have it compute the linear distance between them. This cannot be done in the device because the device cannot sense the horizontal angle. I thought i would use the bluetooth connection but have not because i use a pad of paper and input my measurements into freecad on my pc. The measureon app wants me to use their process and im uncertain how to export raw data from my iphone to my pc, im wary of anything that needs a subscription. In conclusion: this is a rockin good tool. Everything about it is simple and obvious, i never needed to read any instructions. Excellent efficient user interface. The device has the feel of a pro camera. I own tools from a wide variety of vendors and am not a strong fan of any. I do own a bosch die grinder, their big belt sander and their fabulous jigsaw, i love those tools - and i like this measurement device at least as much. $135 shipped with tax and it has already saved me hours. Very very nice. Thank you bosch for the well designed device. The tool feels like an experienced person designed the tool of their dreams. I wish youd sort out the subscription software, it feels like youre giving the MBA/Game Theoreticians too much control. I just need a reliable way to get raw numbers and angles onto my phone, then onto my pc, ideally something that is simple enough to work forever without software support from you. The one invariant of connected devices is that their supporting software becomes unsupported before the device's end of life.

Onsite take off's used to be a pain to do, but not with this little device. I can easily measure walls, no longer having to take out a physical tape measure and measure things. I have saved so much time. It's more on the expensive side of things, but if you're looking for something solid and reliable that won't turn off on you when you'd least expect it, go with this one! It's also got several handy options in the menu, I only use it to measure lengths and heights but I've gone through the settings. Readability wise, screen is just enough. You can see the numbers clearly. If you're getting this for the bluetooth option, I guess go ahead only if you're looking to use a different software other than BOSCH. To keep it simple, their software is horrible (and it costs money for some advanced features). You're better off drawing the blueprints yourself.

Works perfect and connects to Measure Square perfectly. The green laser makes it more visible in daylight. Only problem is, these things keep getting more expensive.

It’s a little more expensive than it should be. But it does work and is pretty accurate. I’ve tested it on the job with very accurate results out to 60 feet. Couldn’t tell you past that. That being said, I don’t trust it enough to not re-measure with a tape if it’s anything important.

The tool is really easy to use, has haptic feedback which turns out to be a game changer, and the built-in level is handy when floors feel sloped and you want to take that measurement as well. The included Lithium ion battery is not reliable and you will need to use AA batteries or carry them as backups. The Li-ion battery has a warning that you can only charge it with a 5v 1amp charge cord, which turns out to be hard to find. I did this and it still errored out with a stop sign when I was measuring houses. I didn't take the plastic battery cover with me, but was able to pop in some AA batteries and just hold them in. Bosch really needs to fix this as a USB-C battery properly implemented is a nice feature. Until then, the tool is amazing, the Li-ion battery is trash.

I work in sales and use this all the time. I have found the measurement from this to every accurate. It’s very handy to go through a project and be able to measure rooms and distances very quickly and accurately. Product is light weight and well manufactured. I like the rechargeable battery and also the ability to use Double AA batteries as a back up. Highly recommend!

This negative rating is not wholly on the device itself but on the inherent misrepresentation of its functionality and the free app. Yes the app is free. Fully functionality requires the app…for $14.99 per month. I think the device is good enough based on my limited use. If a person is willing to pay the subscription fee it might be exactly what was needed for them. The fact that all the functions were touted in the description without disclosing there’s additional charge to be able to use them is extremely misleading. I expected more from Bosch. I’m less inclined to trust them on any product going forward.

Purchased this to use at my Architecture firm and it is easy to use and accurate, perfect for the professional environment

This distance measure works well when making individual distance measurements and it comes with phone software to help you draw room floor plans but to fully utilise its power you should look for third party software that can generate multi floor whole house floor plans. I used Magicplan, but there are many other choices.

Excelente producto, tal cual el modelo que indica la publicacion. 100% satisfecho

We are building a mooring and have to measure over a large area. This is easy to setup, easy to read and easy to see over a long distance. You can also transfer the measurements to your computer where it will produce a 3d shape.

Muy bueno el producto funciona correctamente muy recomendable por otra parte es exacto más no remplaza la cinta métrica convencional.

Sold on Amazon.sg but warranty only in the United States. Unit is not durable at all.
