Review on 📏 Digi-Pas DWL-90PRO Smart Cube Level: Bluetooth-enabled, Wireless Smartphone Leveling Display by Dale Emmel

Good idea but poor execution. First, I couldn't get it to stay connected to my phone app. Sometimes it would disconnect after a few seconds, sometimes after 20 or 30 seconds, but I could never get it to stay connected. Many times I couldn't connect a device to my phone at all, even if the phone and that device were 1 or 2 feet apart. Then after I plugged it in, I couldn't calibrate it properly. I've calibrated this half a dozen times with different surfaces and locations in the building, but after calibration I could only see zeros in all 4 directions. It usually shows a few tenths of a bump in at least one direction, but when I rotate it 90 degrees and try to measure the same slope with the Digi-Pas on a different axis, it shows a slightly different slope. Interestingly, if I put a sheet of paper under the bottom of the pad, it resets to zero. A piece of paper! A sheet of paper 0.15 or 0.20 degrees? Anyway, after trying to use it for a few days I decided to return it before smashing it with a hammer in frustration.
