    • Poor Valve make product useless

      Used for 1 week or less
      Poor valve means both my pumps will not hold and thus cannot get more than 40 PSI. Bike / Tyre requires 65 psi. Adapter won't hold on to valve so even 40 psi is a guess.
      Veryt frustrating. Add to that the vide shows a schreder valve in use and you wonder why. Maybe the video makers could not get it to hold either?
      Bought two. Usually I would drill my rims to use the car type schreder valves but thought I'd give these a chance. WRONG!
      Self healing if it would pump up
      Poor valve, video shows wrong valve for this produ
      Response of the brand
      Hi Stuart,

      Sorry to hear about the issue you have come across with getting the self healing tube to inflate properly. Having used both the 27.5 & 29 version in store I haven't come across this issue which leads me to think there must be a fault with the 2 (batch) that you bought. I would suggest to take the tube & wheel into your local store to see if they have the same issue when trying to inflate over 40psi. If so I'd get them to exchange the tubes for you and fit them to make sure the same problem doesn't occur.
