Brilliant
Brilliant as I say most certainly made a very difficult job go a lot easier. Get the right tool for the right job. quality product which fitted very well and is most definitely value for money. Plus if I ever need to use this item again I have it. It’s cheap and effective plus you won’t have to pay those silly garage prices. Very happy. Thanks. Hope this honest review helps someone else.

Tools work well. Box container is low quality
Tools work well. The box container could be better quality as the latch doesn't lock on at all, so I'm having to tape it down to keep it closed. Just bought it too, so not related to wear

It comes in a compact little box. 5 tools for the price of 1.

Great kit and well made.
Got this kit to fit a Lambda/Oxygen sensor on my daughter's 2005 Ford Fiesta. Good, strong kit and well worth the money. Makes the job quick and easy.

Works as it should
A good set for removing oxygen sensors without too much trouble. The re-threading tool is good for cleaning out the thread prior to fitting the new one.

O2 Sensor Removal kit (Generic?)
I've not used these in anger yet but they look to be substantial in manufacture. Three separate 22mm sockets, 1 x standard 1/2" drive open jaw socket and 2 horizontal drive sockets (short and taller length depending on wiring configuration) to take 1/2" drive long bar, both with open jaw and 2 thread clearing tap sockets. This is a full kit for O2 sensor removal for which 22mm is the standard (I think). Overall, thus far, happy with the purchase but performance yet to be tested. Represents good value for money.

Handy time saving tool
This little tool worked great to gain access to the O2 sensor when cleaning my EGR system. Made life so much easier
