## Customer Reviews

### ⭐⭐⭐⭐⭐ Power tool
*by A***R on April 22, 2025*

I wish the hand start was on the top other than that I love it works with torque great I will buy different power tool made by the same company

### ⭐⭐⭐⭐⭐ Wish I had bought this 3/8" Imapct Wrench years ago!
*by A***R on March 7, 2023*

Love this little tool. It delivers the power into tight spaces. If I can get my fist in there this tool will fit. It has been a game changer for working in so many of these tight spaces. We decided to buy the 3/8" unit vs the 1/2" one by the same company due to it having the same basic power but could easily fit the smaller sockets that will fit into the smaller spaces. One person gave a bad review due to the unit not being perfect right out of the box but then went on to say the unit worked well after a minor fix. Well, mine worked perfectly, straight out of the box and has worked perfectly every time I've needed to use it. The more jobs I do the more I seem to use this impact driver. It feels good in the hand. The air line is quality. The trigger is quality. The main unit itself is beautifully made. The different power settings really help when you want to go easy or crank up the power, depending on what you are working on.It seemed a bit expensive when I decided to buy it but I had seen the videos on this unit and I wanted to try it myself. I had jobs I couldn't do because I couldn't get enough power into the tiny spaces so the jobs went unfinished, until now. I just have to wonder if they will ever make a micro or mini version of this that is 1/4" size. I have some jobs that could use less power but still need to get into ultra small spaces with the drive that impact drivers give.This bad boy is worth every penny!

### ⭐⭐⭐⭐⭐ Robust and in the palm of your hand
*by J***O on September 29, 2023*

The seller was punctual. The product is robust and comes finished. It came in a cardboard package that fulfilled its role, but it's not for life. If you're like me, you're going to use this in a tool drawer, then you won't matter the paper box. The tool is good and worth the money paid, you probably won't have a hand to hold all the torque, so this is a really useful tool for small spaces in the chassis of a truck or car. And it won't replace the normal air guns that have been out there for years. But believe me, when you need it, it will be too late to regret it, why didn't you buy it? It's worth a lot...
