Good product for the price. The base could be redesigned to be more stable when drilling at the far end of the range as the stand flexes too much when starting a large hole over 3” and an extra brace is needed to prevent wobble.
The one piece that wasn’t available is a good interfacing of the bits to the tool, a different adapter should be provided as a 5/8” piece of all thread with a hole drilled in it to achieve the wet drilling abilities advertised is a weak fix to a coupling that could be sold along with the bits to fit the drill more appropriately.
