Punctured a motorcycle tire and pulled out a nail. At first all 5 connectors were glued together inside the holder and were very, very difficult to fit into the tube. Very very difficult to fit in the hole so I had to drill it out a bit. I used a leather punch from a small swiss army knife. Plugged it in and it leaked. Insert a second plug and still lick. I put 2 plugs back in the tire and tried the 3rd and 4th. Both passed. It's $8 down the drain. I got out of the car and took a "sewing needle" with large square long inserts and liberally covered it with tire putty. hand tool. So I don't like Dynaplug and stick with the tried and tested sewing needle. Denial of Dynaplug.
