So far, so good. Its use in energy and its maintenance. Only time will tell for how long. Bought 2 so always had a spare. Will update if or when someone breaks.

Pros
  • Few competitors
Cons
  • Unreliable

DESIGN FAILURE: Spring mechanism too high

The spring loaded adapter tab that holds the sockets in place is set too high. This makes it impossible to install sockets without putting your finger on them so they can slide over them. Other than that design flaw, everything should be fine. Hope.

Pros
  • Easy to use
Cons
  • Poor instructions

Nice addition to the cordless impact wrench 7/16

I recently bought a Milwaukee M18-Fuel cordless impact wrench (2765-22) and used it to drill holes in pipe with Milwaukee self-propelled drill bits. The instrument had more power than I initially expected, so I added this adapter to use with drum heads to control large delays. Some other adapters were a bit cheaper but I've always had good luck with proto tools and so far so good with this item.

Pros
  • Best
Cons
  • Ugly packaging
