Review on 📐 YOTOM Fluorescent Yellow Bubble Spirit Level: 66x10mm Circular Surface Level Inclinometers - Top-Notch Accuracy by Timothy Hughes

I was hoping that given the size according to its own scale it would be more accurate if you used the same surface and rotated the plane 1/2 degree from side to side, even on one On a nearly perfectly level surface, it shows a 1/4 degree deviation, so use it as a reference, but don't expect to align your CNC or gravity 3D printer to it. I took two pictures in this environment with different spirit levels, one picture is just rotated 180 degrees on the same surface and in the same place and shows a big difference.
