Do the job as described
I can now say officially after my first puncture they work as described. Was out on a ride, could hear tyre going down so pulled out my battery powered portable air inflator (another handy tool) and re inflated to desired psi. Off I cycled, had another 10 miles to get home and the tyre stayed up all the way so it does work thank the Lord. Obviously once not riding the tyre went down again as it needed repairing but it got me home and that's a blessing. I'd recommend highly. 👌 this was for a 20x4.0 fat tyre bike.
