Review on UMEI 58MM 79MM Precision Horizontal 79X15X15Mm by Vedavyas Fleming

Looks good but VERY bad. Sitting on the table on its side, it shows a dead plane. Rotate it 180 degrees and it will be halfway between the lines on one side; no, where near. I'm keeping it because I run it with some sort of tape and it will work for my purposes, but if you're hoping for a reasonably accurate level you're better off looking elsewhere.
