I guess it works well, but it seems a little unnecessary. Normal clay works great for windows, I've never had a window scratch or calcium deposits that couldn't come out with machine polish, I've had many a sealant that worked at par or higher than what was given in the kit. basically good if you don't have the equipment handy, otherwise just overpriced.
Pros:-Does it's job.
-Cheaper than collecting professional equipment.
Cons:-Don't buy if you already have a buffer, machine polish, wax, and sealant.
