Circular Bubble Level, Spirit level Round Bubble Level Measuring Instruments Tool Universal Protractor Tool (66x10mm)

A+

I use this to get my canvas and parts level before doing acrylic and epoxy pours. You can tell the bottom was ground to make it flat, but it's not level, so the bubble is never in the center on a level surface. I have to rotate this level in 90 degree increments to get an accurate reading, taking the average of the 4 positions. So while usable if you don't mind rotating the level, it would be nice if the bottom of this level was perfectly level. I may try to 3D print a base for it that is perfectly level, to make this a perfectly level level.

The bottom is angled. If you rotate it over the horizontal surface the bubble will set off from the center.

Total junk. Lost its fluid within a month

I bought this spirit level to set up my turntable, it worked perfectly.

This lacks precision, I purchase this to level a turntable. It always shows perfectly leveled unless really out. Makes it useless for precise adjustments , plus it arrived damaged. Getting a refund but lost the freight cost.
