This review is for the 3/8 stubby triple square impact bit socket set. Upon opening, the first thing I noticed was that you got a pretty decent quality socket rail included with the bits. I tend to prefer this over the bulky plastic blow molded cases since these will usually end up in the tool box. These sockets have held up well to both air and electric impacts rated at 300+ lb/ft. The sizes included are M4, M5, M6, M8, M10, M12, M14, M16.
Pros:
All 3/8in sockets. No need to have multiple sizes on the same socket rail
Cr-Mo Steel. Much more durable than vanadium that the cheaper sockets tend to have.
Super stubby. Great in space constrained areas when you put them on a ratchet.
Sizes are both stamped and laser etched into the socket. Should be able to read the sizes for years to come even when the etching has worn off.
Cons:
The rail itself is nice, but the part the socket snaps into is plastic. Not a big deal as I have plenty of spare socket rails if it comes to that.
Overall, I would definitely recommend these for anyone that needs a nice little set of stubby triple square sockets.
