Bad a$$ tool

If you have this impact you don't need an air compressor or hoses.
February 14th, 2015

Worth every penny

This thing is a beast! Have never had any problems knocking loose nuts or, no air tanks and hoses to move around! Great for getting parts at the junkyard. The ONLY flaw does not reflect on it's performance, but in rather in design. The forward and reverse button is right over the trigger. If wearing gloves (and especially if right handed), it is easy to accidentally switch it form reverse to forward. I have had a couple of times where I was riding on it and couldn't figure out why the nut or bolt wasn't budging. Then I would look and see that my trigger finger had switched it to forward...I was actually tightening it! With it's power, I'm surprised it didn't ring it off! But if you know this in advance, you tend to watch for it, and if it happens, you can quickly make the change. Bottom line...BUY IT!!

Bad ass!

This is one nice impact gun with lots of power and I love the quality. Having the ability to take it on the road for emergencies is really nice plus at home I don't have to drag out the air compressor any more. I was watching a gun on eBay that was slightly used and it sold for just a few dollars less than what I paid for mine new. The outlet store offered a great price.

Best Impact Wrench Period

I was able to change out everything on my car's front suspension with one charge. I changed two wheel bearings/hubs, two cv axles, control arms, two shocks, and both tie rods. This impact wrench only got to half a charge on the battery and showed no sign of stopping. This thing is incredible and I would highly recommend this to anyone.

ir 20v ir 1/2 impact

Probabaly the best impact i own. Im a heavy duty mechanic and work on all makes and modles and by far it is the best amount of money i spent on any of y tools, the only down aide is it is not compact like makitta but compensates with tourque

irw7150-k1/customer service

I had a compressor unit which lost all impact power, i found that this battery impact exceeded my expectations (power and portability).

Additionally, I needed two forms (which I lost) to obtain the second promotional battery. Customer services were professorial and extremal helpful to obtain the necessary documentation to secure proper paper work.

Look forward to future required purchases
