they really good for the price they really fit on my daughters bike

My first time to ever replace a bike tire and I was able to do it. Much cheaper than buying a new bike and it is holding air so I would call it a success!

Two arrived in the box and both are the sizing I requested. I cannot tell the difference between these and others...feel like the same material and I cannot discern if these are any less or better quality. That said, I got my kid's bike repaired and its been 3 months without issues. It's either the tube or the face that my kid hasn't run over something that can puncture it. Time will tell.

Works great. We had to replace in tube in a jogging stroller. This product fit perfectly and works wonderful.

The media could not be loaded. I just put it and use two times and deflate with a hole in a middle of a trip with my kid, what a nightmare. 😡 waste my money and now I can’t return because pass the 30 days. I don’t recommend to buy it . Very cheap rubber material.

Great tubes for a golf cart, worked great. Highly recommended

Easy to install

Two tubes arrived for my stroller. I blew the first one up and it had two small punctures in the tube. It lost air in less than a minute. The second tube did hold air. I installed it on the rim and am waiting to see if it holds air. I won't order this again. I patched the first tube and will let the patch and glue dry, then inflate it to see if the patch works.It's disappointing that a company would send out a product that seemingly wasn't quality tested at all. Perhaps they send out a returned item with puncture holes, and a new tube that does work. It's not worth my trouble to return these. Other reviewers complained about the same issue. I should have listened to them. You should too!
