Good chain tool
I needed a replacement chain tool to fit in my bike bag. This fits perfect in my bag. It is a decent quality tool. It worked well the only time I've had to use it.

False economy - poorly made, wonky and essentially just does not work
Sadly, absolute garbage .. I had hoped for the price it would make do for a quick chain break now and potential very occasional use. What it did was almost damage my new chain and hurt my hands! Pin nowhere near straight/true and nor was the replacement one in the "grip" (which instantly fell off and would never stay on!). I was very very careful to manipulate the chain into the correct place despite the wonky mechanism, but it just could not push the pin out at all and just made the link stiff. The handle is short so lacks leverage (thus the sore hands!). I have used chain breakers plenty many years back but seem to have lost my original tool (Park Tool .. of course!) .. just in case readers think I may not know how to use one. Sent it back and drove a few miles to a friend's house who had a .... Park Tool chain breaker! Immediately and perfectly drove out the pin in the chain with a perfectly aligned tool thread and pin. I hate that they still cost over £30, but it's really the only option.

works fine
works fine, all the other reviews saying it breaks after one use are probably just user error. if your pushing the pin out and it gets stuck, no need to be all rough with it just loosen it a bit, make sure its aligned properly, then re attack. also make sure you tighten the back side in first as that will stop it form bending the link (that was my mistake not any fault of the product)

⭐️⭐️⭐️ Decent tool, but not perfect
The Oumers bike chain tool gets the job done for basic repairs and chain replacements. It worked fine on my 9-speed chain and was easy to use once I figured out the right alignment. However, the build quality feels a bit cheap, and I’m not sure how long it will last with regular use. The handle could be more ergonomic—after a couple of uses, my hand started to ache. Overall, it’s okay for occasional home use, but probably not ideal for more serious or frequent bike maintenance.

Arrived earlier than expected! I'm very happy as I was able to fix the chains of my bikes, only thing I'd say is I did find it difficult to put the chain back together, but I was able to find the solution with some help from my family. Overall excellent product very high quality!
