Order from here thinking it was a good company to work with. I was wrong. Received my order and one item was different from the others. I am one who wants everything matching. Customer service told me to return the item for a refund not telling me I had to pay return shipping. It would have cost about half of what I paid to return the complete complete order as they wood not match. Don't waste your time with this company.
So far I only used it for small buckets of mud with a regular cordless drill. I was a little apprehensive about the plastic fingers and the kind of stiff mud but it mixed it up just fine on the drill's low speed. I haven't tried it yet in a full size bucket but at least I can say that the fingers won't break off, so it will probably work reasonably well. Note that it does not fit inside of a mud pan, so it isn't a good choice for mixing quick set in the pan.
