Query: Poor Quality - Broken bits and a Quik-Lok which will not release a bit.

I have broken most of the drill bits. Often the first time the drill bit was used. The quik-lok will not release one of the driver bits making it useless.My hobby for the past eight years is woodworking. I try to buy the best tools I can afford so I do not have to replace then a year later. I have a number of other Milwaukee products and have been pleased with the performance and quality. However this bit set is junk.
