I managed to get a puncture in rear tyre in a very remote part of the North West of Scotland while out motorcycle touring. The 3 gas cylinders took back tyre up to c25psi enough to let me get to a garage in Mallaig and blow up to usual pressure. Then further 250 miles to get home. Still holding a few days later. As an emergency repair kit it worked well for me. Peace of mind for the more remote roads.
Tyre has seen better days and will now be replaced as was my plan for after this trip to the Outer Hebrides.
