dewalt is always coming out with different combinations of bit sets. they for the most part use the same style cases, with the horrible inserts that makes it a pain to re-insert bits. they lay them out to look pretty in packaging, but they suck to use.
i actually bought some milwaukee shockwave bit sets, and the cases alone are worth buying them for. easy to remove and install bits. sorry, but i;m a bit anal about bits, and hate them being disorganized.
pic i found online showing how the bits pivot out.
