I have one and I am on the 2nd set of wet trim blades but I will probably sharpen them myself from now on. You have to buy the replacement blades as a set of 3, one for wet trim and 2 for dry and it annoys me you cant buy just the ones you need. I dont quite understand why the dry trim blades are serrated and the wet trim blades are straight. I do know a serrated edge is better for a rough cut but I dont know how that plays into it. I can also say the top domes on top are not dishwasher safe with the dry cycle on.
