    Compact and Simple to use!
    I just bought this and it is easy to use, very intuitive. The display is easy to read. The small size is great since it doesn't take up a lot of room in the tool box. When used with the app for the phone it is a very powerful, time-saving tool!

    The measuring wheel I was using finally saw its last day so it was time to replace it. While shopping online I read about laser measures and this one caught my attention. I decided to give it a try and I'm glad I did. Now instead of watching all over the place or trying to measure areas that are hard to reach, I just point, click and measure. Awesome. Just remember that you need to buy one that will cover the distance you typically work in. I would give it a 5 star but it seems like other users have mentioned quirks with the app feature.

    I a real estete appaiser. I bought GLM 50 C in order make simple floorplans with the GLM and an iPad, without paper. The Bosch Apps are not good for that pupose. 3 party apps are expensive.
    I'm sill on pen and paper on location + sweethome 3d in the office. I can't make florplan on site. :(
    Th instrument is good, very responsive and accurate, would deserve 4,5/5 stars, but novadays a divice is nothing without a powerful app.

    Pocket sized and feature rich
    I am a home hobbyist that appreciates convivence. The GLM 50 C weighs less and is less bulky than my "old school" 25 foot measuring tape while measuring more than 6 times its distance. Not to mention it also measures level and angles that I would need two other tools to do so.

    I really like how easy it is to read and appreciate when the screen rotates with its orientation when measuring. So much easier than deciphering the scale on my tape measure. Switching between imperial & metric is easy and important to me because I use both scales for my projects.

    Its Bluetooth capabilities was a major factor in my decision to purchase this. My initial purpose was to accurately capture floor plans to build custom cabinetry. I use SkecthUp for design but still need the initial "as is" measurements to start the process. (I'm not aware of a way to integrate measurements from a Bluetooth measuring device into SkecthUp).

    So why did I only rate this 4 out of 5? I had hoped the free Bosch MeasureOn app would be sufficient to meet my basic floorplan documentation needs, it didn't. After a reasonable attempt at using it I found it too limiting so I'm now using MagicPlan which works with the Bosch GLM 50 C. (PS: Bosch, if you are going to dub German speakers in videos explaining how to use the MeasureOn App to an English speaking audience don’t include both languages in the audio. Also, when you create English only tutorial videos, don’t add an introduction for every 45 second video. Spend more time showing how it works and how to use it).

    While this is a great tool on its own there is another thing Bosch could do to make it better. Allow a user configuration to set the default measure mode on power up. Currently its "real time" which means the laser is on when you power up. Two draw backs come to mind with this. Safety - are people thinking about where the device is pointed when its turned on??? Battery life - I'm assuming the laser is drawing more power when on, why waste energy while the user decides what and how they are going to measure? I've had the device for less than 3 week and am on my 3rd set of batteries. I'm not sure if this is normal as I've taken lots of measurements trying different apps and getting a feel for the device. Battery life was not something I considered when I bought it. Time will tell if it’s a factor. I may post an update down the road.

    Having said all that, I'll keep it and hope Bosch makes it a 5 Start product.

    I was fortunate enough to win one of these from Bosch on Instagram and I gotta say, this laser measure impresses me every time I use it. I honestly did not think it was as accurate as it is, its spot on! It has plenty of other useful features which will undoubtedly come in handy. Bluetooth capabilities and can be used with the MeasureOn app. Bosch sure knows how to make things right, and continues to somehow improve on perfection.

    Outstanding Display
    I bought it to replace an old laser measuring tool. I had no idea that laser tools from Bosch evolve so much. This display is so clear, lighted, big numbers, measurements adjusted in real time, and so much easier to work with.

    I am an average user installing crown molding, it's fantastic! It is surprisingly very accurate and an immense time saver when figuring dimensions.

    Laser is great, app is not so much...
    The laser measure is exactly what I was looking for, in that it communicates with a variety of different apps. Not nearly enough options for connected apps though, since it doesn’t communicate directly with a laptop, if say I’d like to build a room in SketchUp. However, the Bosch MeasureOn app for iOS is just awful. Far too many taps required to enter measurements on a photo, it’s in no way intuitive to ‘just use’ right away as it has a steep learning curve, and many of the important functions are buried too far behind too many different screens that take too long to access. And on top of that, the app crashes nearly every single time I use it, forcing me to re-enter measurements I’ve already taken. That slows me down and costs valuable time on-site with the client. Very frustrating user experience, and not reflective of the quality of the GLM50C itself.

    This works great for measuring. Even outside. What isn't so accurate is the level. If you check for level and get a value of say 0.5 and then turn the level end for end you would expect to see -0.5, but instead you get something very close to what the first reading was which makes no sense. I haven't tried any of the other features yet, so hopefully those are accurate.

    This LDM is very full featured, especially when used in conjunction with the free Measure On app. I like that I can set the units of measure to display just inches and fractions or centimeters only, along with several other display options for the units of measure like meters, feet and inches or feet as a base 10 decimal system. I personally find the inches only and the metric options the most useful. It has very intuitive and easy to navigate on screen prompts to quickly guide me through settings and types of measurement.
