Your review: Good solid set, decent looking case design, doesn't pop open like other styles and should make for a good set if taken care of. This is the nice set that I keep hidden from other workers in the shop since this wasn't a cheap set. I'm sure they are like many other drill sets, if you abuse them they will fail, but so far so good.
Pros: I needed the smaller shank size and this fit the bill. Latched style index case is a nice feature for portable use, looks rugged enough for some abuse. Hinges are riveted opposed to the cheap indexes of old where sections pop out of their hinges that consisted of weak tabs.
Cons: Expensive, but you tend to get what you pay for.
