I use cordless impact guns and airguns every day at work as I do around 500 bolts in and out every day so I need decent bit of kit for my tasks.. this one smashed every competition. It's mega powerful.l! So you have to be careful as it'll twist your hand 😅🙆 I am serious. that's how powerful it is. I went through many cordless guns but this one is definitely best buy I could make . Highly recommended!
