I went to DynaPlugs site to see what the difference was, if any from a regular plug kit. I could not find any mention. You would think if it was the next best thing to sliced bread they would tout the merits of their product.
So for now tire kit $5-$10. DynaPlug depending on the kit $35-$55. Guess which one I will be using?
I can see the idea behind Ride-On - but the last two punctures I have had were in the bit they say isn't covered. Plug kits are becoming a way of life as more vehicles have no spare wheel. OK for a temp fix - but I'd still get a vulcanised patch. Or if near to End Of Life - replace.
