Just wondering if anyone has tried them and if they're any good or any other good puncture protection as I had 1 puncture on the way to work so had to swap out a innertube and then 1 on the way back but was pitch black at 2.30am so didnt have enough light to be able to change the tube again so had a fair bit of a walk before I came to any kind of lighting other than my bike light. Just trying to come up with solutions to try and prevent this happening again. All suggestions are welcome (sensible ones of course lol)
