Good all in one kit
All in one kit that does exactly what it suppose to, great value, easy to use and fit. Versatile kit that removed the sensor and filter without ant complications. Only used it once so I won’t comment on durability

Great for tight spaces and awkward angles
I bought this O2 sensor removal set and it’s worked really well. It fits a standard 3/8 socket, which makes it easy to use with existing tools. The build quality feels solid and it grips the sensor properly without slipping, even on a tight one. With multiple socket types included, it can get into even the most awkward angles, which made the job much easier than expected. Overall, a well made set and excellent value for the money.

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

Works really well.
Not much to say really, works exactly as it should, just what you need to change these sensors.

DAYUAN 5 pcs O2 Oxygen Sensor Socket Set, Wrench Remover Tool and Thread Chaser Set
The chrome socket fitted perfectly for removing O2 sensor on a Vauxhall Tigra (allowing space for cable). I only had my 1/2" bar handy so only used the 1/2" socket. All looks sturdy to last. Great value set

Nice set, great value
OK, this is not a Snap On, (old) SK, or Matco set. I did not expect that for this money. But having said that, as this is a special set not for every day use, i was very happy with the performance for the price. I do not expect them to stay rust free, but i covered them with oil to prevent that. I have read complaints that the chromed socket deforms under high torque. I can believe that. On one O2 sensor i have pulled, i could not get it to budge, so i switch to one of the shorted impact sockets instead, they are a lot stronger, even though they are offset. Any my impact gun had no problem getting the sensor to move. The set works well, and i would buy it even for my shop (that i closed a few years back). I could break a dozen of these sets, and still not have paid for a Snap On set, and the impact sockets would have to be really badly abused to break from what i have done so far. Excellent set. Always REMEMBER to use anti-seize when you put a sensor back in !
