Works well
Good product - however did puncture after a couple months - but could be due to my tires. Pretty easy to install and not bad value for money. Lightweight as well.

Too early to test their durability
These came in Vavert boxes, I've had too return Vavert inner tubes before because they burst when they were first inflated. I haven't used these yet, so I can't say.

Pump It Up
Flat rear tyre & needed a replacement. No local bike shop in the area & these seemed food value.....and they are!

Punctured within a week!
These are poor quality tubes. Both of these failed on me within a week of installing and I ride around 100 miles per week.

Too big!! Thin!
Firstly what is warmth as a category to review on an inner tube!? The tubes are too big. They didn’t fit great. I always do a pre check inflation before I put the tube in after being stung in the past. One of the two had a hole in it! Luckily I only needed one tube. The other was slightly too big once it was on the wheel. I got it fitted because I needed to get to work. That’s why I chose these tubes because they offered next day delivery. About half way in to my ride this morning the tube blew out! Luckily I was on a quiet road. Refund requested! I have to send them back now too. Avoid. But cheap. Buy twice.

What can I say - these are good inner tubes.
