I have this 6465 and the shorter 6464 version of the PB Swiss insider drivers and I really like the compact nature of these. The handle isn't as wide as some other drivers, holds eight bits inside the handle, the bit carousel spins, and the magnet is fantastic. These drivers are actually what set me down the path of ordering more PB Swiss products. I have not had these two for very long, so I cannot speak of the longevity, but hopefully they prove themselves worthy in that regard.
