It does seem to seal minor punctures. However, after less than 1 month of use, it developed a leak around the valve. That's pretty poor, considering the price!

I've got two of these fitted on my bike. It's taken me 2 hours to inflate one of the tyres and the other one won't inflate because the gunk has sealed the valve.
I've tried taking the valve core out and it doesn't help. To get a puncture first you need air in your tyres. These are rubbish.
