Query: inadequate release mechanism

OXO usually makes well thought out products but they haven't improved on the cookie scoop at all unless you count the comfy handle. I bought an OXO cookie scoop last year to help make evenly sized cookies. The thin metal device that is supposed to release the dough from the scoop twisted and bent when working with chilled dough. Once the metal was bent the scoop was completely useless. Ever the optimist I bought another OXO this year since all others I found were plastic. Unfortunately the same thing happened this year although it waited until the fifth batch of dough instead of the third before it crumpled up. Gee, maybe next year I'll get seven batches out before the thing twists and bends! My opinion: comfy handles don't count when the release mechanism is made so cheaply it is useless.
