Easy to clean, easy to use. Only complaint is that "piston" is too small for the cylinder it fits into so when you press down hard to get your hamburger, hamburger squeezes out the gap and you can't get a dense enough patty. I fixed it by wrapping tape around the flat disk part (piston) to make it fit tighter and that worked. Overall a great product, well made, strong, durable, I'd buy again.
