  • Great buy for the weekend repair guy
Style: 1/2" Impact Wrench
I wanted an impact wrench for all the weekend vehicle repairs I do, but didn't want a pneumatic setup. I also didn't want to spend the $300+ that my mechanic friends spent on their cordless impacts. This impact, combined with a 1/2" master impact socket set, is the greatest tool. It saves so much time, and makes taking off rusted bolts a breeze. I haven't tested the actual torque rating, but no nuts or bolts have been able to beat it yet. 1 Year Update: I have been using the impact wrench for a year now, almost every weekend. It looks a lot worse than it did originally (covered in oil stains and has been dropped a time or two), but it still works just as well as it did when I pulled it out of the box. The battery will easily last me for the projects I do. I replaced the entire front end, wheel bearings, and struts on my truck and still had half the battery left. For anyone who is looking for an impact wrench to use here and there, I would highly recommend this one. 3 Year Update: Still works great. I bought a high torque impact that uses the batteries I have for a lot of other tools, so I now keep this in my trunk. It has come in handy for helping others change flat tires quickly. If you don't have a preferred brand and batteries, this impact is great. ... show more

  • Very good product.
Style: 1/2" Impact Wrench
I don't remember buying a product that last as long as this wrench here in amazon. I have for 5 years now in February and it's very strong. I'm a track day instructor guy and have been using this impact wrench all this time with no problems at all.

  • Good impact. Long term review.
Style: 1/2" Impact Wrench
This is a long term review. I bought this impact gun in 2020. I bought it to keep in my travel trailer if needed. The few times I have used it it has performed flawlessly. The thing that’s impressive, is the battery. I have gone months with it just sitting in the trailer. When I check it now and then, the battery is ALWAYS fully charged. I even plug it into the charger to make sure it hasn’t drained any, and it charges for maybe 5 minutes or so and it’s done! If I had to complain about anything, it’s that you can really smell the motor when using. There doesn’t seem to be any issue with this, it works fine. But it does stink some. HIGHLY RECOMMENDED! ... show more

  • Battery died after 5 months - Update
Style: 1/2" Impact Wrench
When I first got the driver and used it, I was happy with the performance and battery life. Overall torque was good (checked against Snap On torque wrench) and consistent. I use this as an emergency tool when I travel with my RV trailer and used it about 8 times over the last 5 months. Today I tried to use it and the battery was dead. Nothing shows on the battery indicator and steady green light on the charger. Not sure if it’s a bad charger or battery. I have contacted the manufacturer so we will see how that goes. Right now it is a useless paperweight and I am not spending $61.00 to buy a new battery. I have DeWalt and Makita battery tools that the batteries last years in some cases. I will update when I hear back from the Manufacturer. Right now I can not recommend just based on it breaking so soon after delivery. (Check last UPDATE) UPDATE: Amazon not helpful. Had to go direct to Neiko. After a week they ask for recpt and picture which I sent the next day. 3 days later they email me and say they will contact me when my replacement ships. Sounds good right? Two weeks...nothing from them. I reach out again, nothing back in response. Crickets. Even more frustrated with this manufacturer with the lack of communication. LAST UPDATE - A new replacement tool showed up today via Fed Ex. They did not tell me is shipped but I guess they handled it and here it is. Brand new. I have not tested it yet but I am assuming all in good order. I have changed my stars to 4 stars because their Customer Service did follow up and provide replacement with not too much fuss. ... show more

  • believed some of positive reviews
Style: 1/2" Impact Wrench
yes value for money. first impact wrench purchase ever. took a long time to decide which model to buy. wanted it for automotive work and building fence. charger and accessory nice, but I gotta say the item did not work. I could not believe it. batt fully charged and tried to loosen typical 12mm nut on a car. made noise but no torque at all. I knew right away that this one is a defect. after years of being Prime member, my first return ... customer service, the best. rep was easy to get hold of and chatted 5 minutes. and he says I'll get the replacement next day. I chose replacement rather than refund. I made a good purchase as I do believe many positive reviews to be true. so got the replacement and tried it out. worked great. this will be my only 1/2 in impact for years. name brand tools sooo expensive. and I do have Makita and Dewalt pwr cordless tools. Dewalt blower amd Makita multitool ... these are best tools I ever had. worth the extra cost. For 1/2 in impact cordless 20V and cordless grinder I went with cheaper brand. happy with those cheaper brands too. one more thing... Kimo cordless reciprocating saw was a great buy. Returning the defect item was easy. went to UPS Store and printed return label and shipped it out. I only took out the impact wrench out of the replacement package and put the bad one in. will goto UPS store. easy return process made me happy, so 5 stars ! ... show more

  • Good value, perfect for wheel changes and lug nuts
Style: 1/2" Impact Wrench
I bought this to speed up my twice yearly job of swapping winter to summer wheels on our cars. Don’t need a Milwaukee for this job.. It worked great. Plenty of battery life to get through two typical small SUVs. It had no issues loosening the lug nuts which I tighten to 140 nM / 103 ftlb. It made quick work of putting the tires back on. By just barely pulling the trigger it quickly tightened the lug nuts up to just below spec for me to come and finish with my torque wrench. Time will tell on the durability.. but it feels sturdy enough. For my occasional use I expect it to last me a long time. I also really like the case it comes with. I wish more tools came with a perfectly fitted case to keep things together in. ... show more

  • pretty good
Style: 1/2" Impact Wrench
i've had this for about 5 years and it's held up pretty well. granted it hasn't lived a very tough life, i still think that for DIY work this is pretty good. though if you do professional work this maybe be a bit underpowered for what you need.
