Worth every penny!

I was in the process of buying a ***p *n 1/2" cordless gun and the jobber jerked me around and never got it for me. I called his corporate office and that was a waist of time. Then I went on Google and found this 1/2" drive impact cordless gun (IRW7150-K2) and watched the videos with IR against ***p *n. I was very impressed with the video. Then I went to an IR jobber here in Houston, Tx. and this gun was kind of pricey. I went back on line and found Factory Authorized Outlet and their price was way less and with the free shipping and only 4 days to have it delivered, it was worth every penny. The "PRO" of this 1/2" impact, I have not found anything that I have used it on "NOT" remove any nut or bolt from a 3/8" to 1 1/2" socket. One battery usually last me all week on one charge. The "CON", like I have read in everybody's review, it is a little on the HEAVY side. However with the power it has, the PRO outweighs the CON. I am a heavy duty wrecker driver and I use this tool everyday. Now I can kick myself in the rear end for not purchasing this tool sooner. By not having to drag out an air hose, this 20V cordless impact has speeded up my work time and job performance.

Flawless Performance!!!

I bought two of these units to break down and remove a 15in gauge railroad that had been sitting in the ground, in the Northern California mountains unused for over 30 years! We removed over 1500ft of track that was mostly buried in the ground and used the guns to remove the splice plates on each rail junction(over 600+ plates). Each of these guns performed perfectly! The power of these guns is incredible and the batteries last a very long time and with one battery on the charger I was never without a fully charged battery. The bolts we removed ranged from 3/8 - 3/4in bolts and nuts. Most of which we were able to twist off with the 780ft of torque these guns provided. All in all this product is first rate. I've recommended this impact to everyone I know!

Very high torque

Extremely powerful cordless impact. The free battery promotion makes it a great deal. It is a little heavy for working on your back for long times, but great for any external bolts, e.g. lug nuts, suspension points, etc.
