Good deal. Prime is definitely worth it, especially if you also get Amazon's Store Card because you get 5 percent back. (Just pay it off every month, though, because the interest is crazy high.) I think my Amazon orders have quadrupled since I signed up for Prime and I don't have to worry about shipping on most items anymore. It's a good deal. Plus you get Prime Video, which has some decent titles included.thanx for the tip...just ordered one...signed up also for the amazon prime so in the end it cost me under $15.
I've heard some people say that they eventually lose their accuracy due to work hardening.So...I answered my own question with the help of Google.
Seems it's all about the flex point!
I always wondered why the sticks don't eventually sheer from over torquing but it seems they are smarter than I?
I should have mentioned that the impact wrench does NOT include a 21mm socket, and the 13/16 was not "close enough" to use on my Soul's OEM lug nuts. No biggie. I picked one up locally for less than $7.00 from my local Carquest store.Another good choice
Run down to your local Harbor Freight Store and pick one up... Highly satisfied. Comes in a real nice Carrying Box. (read the Reviews for tips on using a Impact wrench correctly.

1/2 in. Heavy Duty Electric Impact Wrench
Electric Impact Wrench - 1/2"
Review Sample: Good sockets required.
First off this wrench provides awesome performance at a fantastic price. Reading some of the negative reviews i can't help but think many of these people simply aren't using it correctly. Two points. One, if you want it to be powerful, you have to provide it power. That means no low amp lamp extension cords. If you need an extension cord, use a heavy duty large gauge cord, and keep it as short as possible. Two, use good quality impact resistance sockets. The whole point of the hammer is to transfer shock waves down the bolt to the threads. To get those waves to travel you need tight fittings. If you are using regular sockets that are more prone to absorbing that energy instead of transferring it, you are losing power. Use good quality impact resistant sockets. In the same vein, using socket extensions doesn't really work. You are just increasing the distance for that energy transfer to happen. The longer the extension, the more power you lose. And don't even think about using socket adapters. Adapters only add a new gap into the equation. Waves don't want to cross gaps. It's a 1/2" wrench, use 1/2" sockets. Good luck.
