Query: Design flaw

The metal foil piece is a neat idea, but you have to remove it often to make sure the blades are clean and the hair isn't stuck in it. The foil piece on mine broke where it attaches to the main handle/body. It doesn't work so great when it's wet, and so I'd suggest to stick with using this product when dry. Battery life could definitely be better as well. For a remotely close trim, don't use the attachments. Otherwise, it works but I'm sure there are others out there worth the money.
