Simple and Excellent Laser
I use this laser measure for architectural surveying to create asbuilt floor and ceiling plans. I work alone and use a laser measure and a sturdy 25' measuring tape. For 10 years I had been using a very premium but heavy bricked sized Leica measuring laser, until I met a contractor in the field who had a pocket sized laser like this. I was surprised at how small they were, and in the last couple years, how affordable they were. So I made the jump and purchased a different laser from this one two years ago. However, its battery life was a little sporadic, there were a lot of features I didn’t need, and it could only measure to a 1/16 of an inch, which is more than I need. You could also change the reference point of where the laser measures from (moving it from the rear of the laser to the front). This is not helpful when you can change it without realizing it. So recently I was researching newer lasers, since I was not satisfied and I found this GLM100-23. I spent time comparing it to some of the more expensive Bosch lasers, like the one with the green beam, but eventually decided this one. I measured with it yesterday and was so pleased with it. I love the fact you can adjust the fraction amount to what you need – gone was my mental math to assign a decimal value to 1/16ths of an inch (its faster to write down the decimal than the fraction). The screen showed one measurement at a time, but was so legible! The other laser had a screen that would time out and then it became hard to read. This laser has white numbers against a black screen that doesn’t time out! The laser is so small and lightweight, you can easily hold it and the tablet at the same time. Lastly, the reference point for the laser can’t change, so there’s no way to fudge up the measurements you need. Overall this laser is EXACTLY what I needed. Also, a note: the "click wheel" is an internally displayed menu that allows you to change the measurement option (from feet, to inches, to centimeters, to millimeters, and then feet as displayed 0'-00"). You access it by long pressing the fraction button.

    This is easily the best laser measure tool I have used in the past 15 years at this price point. I measure real estate, hundreds of properties a year and have used many different brands of laser measure from inexpensive cheapos to expensive trying to find one that is accurate, reliable and easy to use. This Bosch Blaze GLM 100-23 is the best for the price offering base level measuring with the ability to change the type of measurement from Feet, Inches, MM, CM and others. I was skeptical due to the price but wow this is the one for me and my needs. Very clear and easy to read backlit screen, accurate, easily fits in my pocket, has a place to attach a lanyard which makes it easy to pull out of my pocket. The screen is bright and has a bright laser that I can see in sunlight. If your looking for a budget friendly design with good utility, reliability and is accurate you cant go wrong with this one.

    Cannot say how many times this little device saved me time and effort! Very accurate, low power consumption - batteries last quite a while - and somewhat easy-to-read display. In fact, My only complaint is the smaller numbers are very hard to read. For longer distances where a tape measure would sag out on you, this puppy can't be beat! In fact, I use it in places where I could use a tape just because it is more accurate than my eyeballs reading the tape or because I'd have to bend the tape at the end and guesstimate. Obviously, I would highly recommend it.

    We are in the process of obtaining a new place and for once, I wanted to have everything worked out before the move. After checking out several options we settled on this Bosch Laser Measure. I love the ease of use and how quickly I was able to measure the space we have, the furniture and other details so I could plan the entire space.

    PROS
    - Easy to use
    - Accurate measurement
    - Save feature to keep your measurements on hand for reference
    - Small and portable

    CONS
    - I would love it more if it had away to measure without a point place. For example, in measuring my couch, I have to put a piece of paper at the other end and point it there. Ideally, I could set the point place and walk back from there to get the distance. But, maybe that would be a much more expensive tool.

    Overall, I recommend this measuring tool.

    The good thing about this Bosch GLM 20 is that it’s compact and less complexed. For people who need Just 1 button to tell the distance.
