Review on Performance Tool W1 Metric Wrench by Srinivasan Bennett

Looks like a useful wrench to keep in the trunk. The wrench (at least the one I have) seems to be a bit bigger. I have too the metric option and the included sockets are interchangeable, but the metric sockets fit a little tighter on the SAE stem with 1/2" male thread, 3/8) but the adapter is 1/2" with x 3/8 "Female x 3/8" male thread is too tight for an SAE socket (however, this adapter is ideal for metric wrenches) a different brand 1/2" head, but you may have to work hard to fit attaching (and detaching) it. Good luck.
