The instructions are difficult to understand, the pictures and instructions do not correspond, and it was difficult figuring out how to assemble it. After I finally got it assembled and working it performed great. I accidentally cut into one of the dogs and destroyed the blade. The water tank leaked and I called about it and explained about sawing into the dog, the tank and the dog were replaced. I ordered new blades at the same time, and was told it would take two weeks for them to be delivered. It has been two weeks and I have not received them nor an email telling me when they will be shipped.
