Was getting a leak around the valve stem on a mountain bike. After put this in it fixed the issue. Great product. Need to sell it with larger quantity.

They are inexpensive and they work.

Works great !

Yes I will admit these things are a great deal. But with their low price they lack durability. I set them up with no problems but soon realized their weak points. If you do not fully tighten them to the rim they will leak a lot of air quickly. Overall if you are looking for a quick way to go tubeless these are a good options but if you are serious about cycling I would dish out an extra 10 dollars and go with a nicer pair

Its cheap and it worked!

Works great, great price

Sealed well. No issues. Included tool was useful and stays in pack

The valves are absolute garbage.. Wish I could leave no stars at all. They leaked, tried everything under the sun to make it work but they’re useless.. I would not never buy it again..

Easy to install and, so far at least, properly functioning, these valves were installed on wide rims for 2.8 width tires, using Gorilla Tape to seal the rims for tubeless conversion. No leakage, and no clogging, as yet; but its only been a week, so I cant yet comment on any long term experience with them.

Bought new wheels and tires, and I needed stems. These were reasonably priced. I had no issues with them at all. The included core remover is also a nice touch.
