Zengi Gunsmith Magnetic Level System, Pack of 2

According to these, my desk is both level and not level at the same time

It's hard to find a good level for mounting my scopes and I thought this might be it, but the magnet is pretty weak and accuracy is questionable. I'm relying on the Arisaka mounting system instead. Would I buy again .... no. The base of the levels have some weird angled cut-outs which "I beleive" cause accuracy issues. I have some other non-magnetic cheap scope levels that appear more accurate when I measure against an actual mini Husky construction level. I do not recommend for checking the level of a scope.

These things are cheap looking and that look is not at all deceiving. The magnets are tiny and not very strong at all. I have refrigerator magnets for my kids that are stronger.As for the leveling itself both products perform poorly with very tiny bubbles that leave a lot of room for guess work . I want my money back but I'm not sure it's worth the effort. Look somewhere else.

Placed on the same flat surface, the units read differently. From reviews I've read about these and other inexpensive levels, this appears to be a not too uncommon problem.

Neither level seems to be exactly level, but it isn't worth the cost of returning it. I think I'm going to move up by a price point and see if the quality improves.
