    • Didn't work. Twice

      R (United Kingdom)
      Used for 3 to 6 months
      I have followed the instructions on two separate occasions, and it did not work. The material remains as liquid, and loses pressure.

      I notice most reviewers have used this as a precaution. I used it after punctures.

      (I would suggest to the manufacturer, to put on a firm screw top or locking lid to avoid accidental activation)
      Neat packaging. Clear instructions
      Does not work. Messy

      Dear Sir,
      Thanks for posting a review of this product. You are correct in saying that it is designed to be used as a preventative solution. You put the correcta mount in your inner tube and then if you get puncture, the liquid will seal the hole as you are riding. It is not a post puncture solution.
      Some inner tubes already come with the solution inside and cost £3.99 each and can personally recommend them folloing a thorn on one of my rides which under normal circumstances would have caused a lot of hassle but on this occasion (after a few hisses) it simply sealed itself as I was riding along with a very small drop in pressure. When I returned home, I repaired the puncture. An excellent product for long rides, regular commuters and sportives.

      This popped my front tyre that didn't have a puncture after I injected it into my tyre for protection.

      Super weird and annoying. Avoid.
      Response of the brand
      Hello Sir,

      Sorry to hear that you have had an issue when using this product. It is as you say very strange that the tube has popped after installing the liquid into your tube. If you go into your local Decathlon store they should be able to sort you out with a new inner tube and tube sealant as the product hasn't worked as it should have done.
