### ⭐⭐⭐⭐⭐ this solves your problems for sure.
*by  on Reviewed in the United States 11 June 2026*

I was looking for security because I am a 60 year old disabled man and this bike is the only exercise I can do and if I get a flat, I can not walk and i have no one to save me. I would not be able to get home. I put this on and installation was easy and never had a flat after and was able to feel ok about going farther from home. This is what I needed and I was able to feel good about riding any where without worry of being stuck. You will not be sorry if you spend the little extra for this because it solves the problem that takes you here. Unfortunately for me, I was riding my bike and was struck by a tesla and I was in the street with my shoulder out of socket trying to get up because my knees were burning on the street,. I asked the driver to please help me my knees are burning and they sped off and left me. I never knew people could be like this to anyone. I had to lie on my side and roil myself over out of the street cuz it was a very busy main street and nobody even tried to help me They just waited for me to roil out of the way and someone got my bike and moved it and the wheel was all bent and now I am saving money for another bike because I cant walk and need exercise. I know I will put these inserts in my new bike when I can get one.

### ⭐ TOTAL RIP OFF!!!!!
*by  on Reviewed in the United Kingdom 15 October 2022*

For £134 i expected to get x2 of the 26x4" armor, unfortunatly i was wrong and only 1 turned up, have spoken to tannus uk and the price for the 26" armor is £50 per item, trying to return the item isnt the best either, they require you to pay for return shipping which for the price is mad.avoid at all costs!!!!!!!!

### ⭐ Price is for one liner
*by  on Reviewed in Canada 22 October 2025*

For $155 I thought it was for 2, a set of liners. It's $155 for one piece of foam?! Insane...never would have ordered if I knew it was over $300 for 2 pool noodles.
