I originally ordered this laser-measure to do rough estimates but not for making serious lumber cuts. When it arrived, I couldn’t resist putting it to the test versus my trusty tape measure.
***This thing has amazing accuracy! (See photos)***
Repeated measurements without moving the device seem to render the exact same result with no deviation. It’s easy to select your measurement reference from the base of the device or the front of the device. You can select Metric (Display:1.313m), Feet (4.308’), Inches (51-11/16”) and Feet-Inches (4’03”-11/16). And, YES, when you turn it off and turn it back on, it does remember the mode you last selected! If you forget and leave it on, it will turn itself off automatically to save your battery.
The plastic case is quite solid and the buttons have a good quality feel. It comes with two AAA batteries, lanyard, belt clip, soft case and an instruction manual in multiple languages including English. I believe the manual covers everything you need to know, but this thing was so intuitive and easy to use that I was able to easily figure out all of the advanced options without reading the manual.
The laser brightness for measurements is probably adequate for most indoor applications. Generally, if you can see the red dot you’ll get your measurement. Even when the red dot is barely visible, because of ambient light, the measurement seems to work fine. If you need outdoor measurements on bright sunny days, this probably isn’t the product for you. (It’s after dark when I’m writing this review, so I couldn’t resist going outside to push for a long distance measurement.) 179’01”-13/17 (photo) was the last of multiple measurements at different points along the white siding of a neighbor’s house. Generally, if you can see that red dot you’ll get your measurement.
Next, I decided to use the advanced functions to measure my flagpole (about 30-1/2”) and Blue Spruce tree using the Pythagorean method (photos). (The built-in bubble level is handy for the 2nd of the three required measurements.) This is a really cool feature and it works quite well.
Overall, I’m impressed with this laser-measure. For such an inexpensive product I was pleasantly surprised with the accuracy, ease of use, features and build quality. Highly recommended!
