When you buy a compass, the only thing that matters to you initially is for the indication to be accurate. This does not apply to this one. Now, if everyone intervenes and fixes it, okay, but I would prefer it to be reliable from the beginning.

This level is not properly calibrated, resulting in the need for adjustment by anyone who wants to buy it. I adjusted it by adding 3 screws to the corresponding holes it has and set it up so that when it is turned 360 degrees to be perfectly horizontal, the bubble shows in the center.
