Accurate according to my calipers
Tested the accuracy with my calipers and both blocks were dead on. Much more accurate than I would need for woodworking but it’s nice to have something so reliably accurate. Blocks are heavy too so that’s nice. Only “flaw” if you even want to call it that is that the holes aren’t drilled with the same accuracy…2 or 3 were slightly off center compared to the others. But I have no intended use for the holes so this doesn’t affect me.

Awesome blocks. Very accurate and a great price
Taytools makes a great product for a great price. You can’t go wrong with their stuff. The 123 blocks are accurate and appear to be well made. I’m so glad I got a pair.

Cannot be bolted together
The blank holes are too small to pass the threaded bolt through to bolt the two blocks together
