I purchased 2 Halfords 150 piece professional kits about 5 years ago, I keep one with the race car and the other in my daily driver.
The race car is a Honda but many of the after market parts are manufactured in the USA so I have the occasional need to use the other side of the tool kit.
I really can't grumble, both kits have proved to be excellent value for money and really get me out of trouble as well as many other people at the track that just don't have enough tools with them.
To date I broke I racket extension, the lock pin fell out as it was a poor design, Halfords changed it in shop for an improved version with a ball bearing instead of a pin, both kits have seen a lot of use and show no signs of wear, just make sure you look after it and keep it dry.
If the rain gets to the kit then dry it and spray with WD40 to stop the rust getting in, then again, if it breaks just get a free replacement.
