I've used these before and I've changed plenty of tires so I'm not a rookie. I was careful, and gentle, and the cable pulled out of the handle on my third tire change. I won't say it wasn't due to anything I did, but I do think this could be built a little sturdier. That said, this is a really handy tool to have when you're changing tires. Just be careful not to pull too hard.

First time I used it, the (very thin) cable pulled out of the handle.

Bought the tool thinking it would make life easier changing tires but the low quality tool broke during the first use. Pulled slightly and the wire pulled out of the stem tool. DO NOT BUY

no more battle with the valve stem!

Great idea. Was really looking forward to a tool that would make this difficult job easier. Threaded cable through wheel, screwed into the valve stem, put tube in wheel gave a very slight tug, and the cable came out of the handle on this tool. OK, I though, that stinks, but I'll just use pliers this time and rig the cable back to the handle when I am done. Grabbed pliers, grabbed cable with pliers, pulled lightly, and the cable pulled out of the valve stem end of the tool. Did they attach the cable with shewed bubble gum or elmers paper glue? This would be great tool if it had been built well. Unfortunately this tool is built terribly. Now I am left with an overpriced valve stem remover. Motosport needs to stop selling this right now. Selling junk like this is bad for their reputation.

Core remover worked fine, but when I went to pull the valve stem through the hole, the wire pulled out of the handle. I grabbed the wire with my safety wire pliers and it pulled out of the other end too. This made me have to unmount the side of the tire that I just got on, and I had to smash my fingers trying to get the valve stem through the hole the old fashioned way.

Makes it so much easier getting the valve through the rim, particularly on narrow rims when you have large hands

It is ok don't pull to hard you get about 25 tires changed before the cable breaks
