Only takes Type 27 cutoff wheels, not Type 1.

I like the Hart tools, including this one, and being able to use the same batteries for all of them. I didn't read everything before buying this one, which I intended to use for cutting up some small metal tubing, and I was disappointed to find that the Hart cutoff wheels that Walmart sells don't work with this angle grinder. It takes only type 27, and the wheels are type 1. That's nothing against the angle grinder, but I think others would also assume that the Hart disks would work with the Hart grinder.

Good quality and crisp operation

I like everything about this so far but I used it twice only yet so that's quite a limited experience. I seem to like the quality and operation, they seem to be crisp and clean and free of unnecessary protruding parts. I like also that it with the 20v system so I did not need to buy extra batteries as I have 4 already switching between my 5 hart tools.
