alright
The price is good, and the shipping is fast; but the durability of the tubes is not as heavy duty as it says. These will be my second set!

There may be a manufacturing defect
I purchased the 2 pack.one works fine so far the other not so much LOL. If you can see by the pics there is definitely an issue with adjoining valve stems. That is probably why most of the bad reviews say they will not hold air. I would be willing to bet that if you were to add some rubber cement around the base of the valve stem it would work like a champ.Im hoping to see if they will send me another tube hopefully for free. I'll give an update if they do.
