Good tool at a good price point
Bought this to replace several parts on my car. It was worked like a beast and did the job very well. The only issue I had was that it seized up while breaking a nut loose on a ball joint. After working it free it felt a little bit like there was some loose metal that got shaved off of maybe a ball bearing inside the drive, but after a while it worked fine again. I probably should have gotten the warranty on it just in case. The battery lasted quite a while too. I only had to charge it once for the whole job (replacing the front knuckles and tie rods on both sides of the car). The size of the gun was good too.

Big, bulky and badass
A retired mechanic and so use to air tools. Hard to carry an air compressor so I purchased this for the name (yet it is nit what they use to be), price and reviews This was a major change for me as a air tool is quite lightweight and this is bulky and much heavier. I had to change all 20 of my old lug nuts with new and was gonna do 1 at a time. This had no problem. Reason I needed this as the tire shop overtorqued them. I struggled with the chincy jack handle and realized I needed to get my old torque wrench, anti seize and a new impact. This did the job. The low speed was good to run down with minimum torque. Fully charged before use and still gas all lights when battery was checked. The bag is kind of thin so I can see that getting worn with age quickly. The trigger action is variable like a air tool. One thing I had to get use to is when you release the trigger from full, it had a brushless delay unlike pneumatic tools. That was my only issue. Now I plan on getting a craftsman 3/8 relatchet that will accept the same battery (if possible, leave comment on model #if so) As I do a little tinkering for myself on cars. My ingersoll rand composite air is a jewel but that hose only goes so far and this impact fits in my trunk. The spare tools the manufacturers put in spare tire well are 1 time use junk and it is best to be prepared when needed. This fits that bill.

the stronger batter gives more torque.
So I got this for a friend. The cost was unbelievable so we had doubts about it, but I can say it works great. The battery charges fast and lasts long, is easy to use, good power too. I did not expect it to do the job, the size is great, easy to hold in hand.

Great Christmas gift from my wife!
Have only used it once., but head and shoulders above my air impact tool. I love it. No Electrical cords either. Quality seems to be right there. Sure does look identical to a lot of other ones on the market. We have Craftsman weed trimmer that seem to hold up. The last one was battery operated with 20 Volt battery pack. So I have plenty of backup battery supply. Delivers fabulous torque both in removing a nut or installing one.

Good for everyday use
Powerful enough for smaller jobs on my cars. Craftsman has always been a reliable brand for me. I have better cordless tools but Craftsman gets the job done for most of my needs.

Works well
It works well. I had no problem taking off the lug nuts on my '09 Sierra. I'm glad I bought it back in Feb, 2005. The price has increased by $100 since then.

No por nada craftman tiene su prestigio. Se la compre a mi papá que es mecánico y le ha funcionado de maravilla, anteriormente había comprado otras en tiendas automotrices y no le duraban sobre todo porque eran de carbones y tenían menos fuerza. Esta afloja prácticamente todo tiene muy buen torque. No ha dado problemas y eso que la usa en trabajo pesado no se ha descompuesto y la pila dura
