Seams to be plenty of different types on the market, I bought one from Hien Garick about five years ago, I have used it a couple of times getting other people out of bother. When I recently used it myself I found the remaining rubber bungs had perished,

So before I order a new one what if any do you guys recommend, having actually used one of the kits.
I am about to order a kit made in Europe by GRYP it uses no glue instead has a soft round tacky strip, I assume it hardens with contact with the air or heat.
