Review on GemRed 82412 Mini Digital Level Angle Gauge: Accurate Aluminum Protractor With Magnet by Vijin Wisniewski

The angle finder does its job well, and it's not complicated. For the price, it's as good as you can expect or want it to be. The only change I could ask for is clearer indicators to show whether the measured angle is left or right of perfect vertical, as the triangle arrows on this unit just point up or down, which isn't an intuitive way to show it. A diagram of an acute angle opening to the left or right would be much more intuitive. It is fairly sensitive to being tilted backwards (roughly 10 to 15 degrees backwards is enough to make it return an error), but it at least shows 'Error' until it is orientated properly, rather than giving an incorrect reading. I've had this for about 5 months and use it for about an hour once or twice per month - so far from heavy usage, but that's enough to determine that mine hasn't died on its own and it doesn't rapidly drain the battery when not in use.It's inexpensive and it does its job well. If you are reading this review, then that is probably the criteria you are looking for. If I needed a 2nd inclinometer, I'd buy another one of these.
