## Customer Reviews

### ⭐⭐⭐⭐⭐ Did The job very well
*by S***N on 12 November 2023*

I had a job on a van and it did it very well

### ⭐⭐⭐⭐⭐ Quality products budget price
*by K***. on 18 May 2023*

I have had quite a few Us pro tools and this one is my latest acquisition . They make good tools without the huge price , the quality is good and they seem to last .I have broken many tools in the past because I’m ham fisted but these seem to take the punishment well for a reasonable price . I am an occasional mechanic not professional by any means but buoy can pay a lot more for tools thanks these and they do the job well .

### ⭐⭐⭐⭐⭐ Should handle most things
*by R***N on 28 August 2020*

Garage overtightened wheel nuts on my car. Snapped a 1/2” breaker bar trying to undo them. This 1” bar overcame the problem with ease, although not without a huge amount of force. Car now has new set of studs all round as the old ones are probably unsafe.Have a tractor to strip down in a few weeks time and am expecting this to make short work of any high torqued nuts. Will follow through on this.
