What people don’t love

Outside cutting teeth can cause difficulty when re-centering the bit after clearing debris.
Not as sharp as some would prefer, though it avoids burning the wood.

Some users report it doesn’t work well on very hard or dry wood.

Sharp and well-designed bit offering great value but with some size inconsistencies and minor usability quirks.
