"This is an excellent tool to have in you arsenal, there's nothing worse than having to replace a back box just because the threads are nackered especially if you've nackered them and not the customer. If you only use it once it's worth the money. Buy one now."
"Don't normally write reviews but this little gadget cannot be faulted , especially for the price. Managed to knacker the fixed lug side of a metal back box sited very deep in the wall and faced a bit of a nightmare if having to change box completely. Have had similar problems before but not from now on. A few seconds with this and all sorted taking screw no bother. Brilliant - how did I ever mange without one of these before."
"best tool to have kicking about in your kit, especially when on site after the plaster has clogged up your metal back box and you need to re-thread it and clear it out. quick and easy to use when time is money."
"This is an easy to use tool which can save a lot of messing about when a socket box thread gets damaged. It works well and is reasonably priced. The only very slight criticism is that it could be just a little longer."
