As the description states this is very useful glue to have around! You can use it to patch or fix anything rubber or synthetic which needs to be flexible. I've used it to repair rips in my down jacket and patch holes in rock shoes. It does take a day to cure completely so to say it fixes holes and rips fast isn't quite accurate. Once cured it is very strong and durable, although it doesn't last long on rock shoes but can get you through a session if you're desperate (it makes you realise how much force you put through your shoes when climbing!). Once opened you need to keep the it in the freezer or it will cure in the tube.
