Very pleased with this product and I am buying some for Christmas presents. Wouldn't want to be without it now.
I replaced the handle/knob on a steel splatterguard and it has stuck for a few months not fallen off yet, I am using it on top of hot pans on the hob. Previously the old handle fell off and I was having to lift it with oven gloves which was a pain.
I have also mended a le creuset casserole ceramic pan lid that had the handle broken off. I made a new knob and it has been working for a few months even though the lid is quite heavy. It hasn't fallen off and has been through the dishwasher. Haven't tried it in the oven yet.
I mended the plastic candle holders on a Christmas window light, they now stand up, 2 out of 6 were snapped and keeling over requiring a bit of force to hold them in place, but the sugru worked. Saved having to buy a replacement set for £30.
It doesn't stick to rubber (or claim to either). I tried it on my cut off welly boots that have a cracked seal and it doesn't stick at all, so that explains one of the other reviews.
I just opened a pack that goes out of date in a months time (I have had it ages) and it had started to go hard around the edges, I could still use the majority of it no problem but I wouldn't expect it to keep much out of date, fair enough but worth knowing. I wouldn't expect to keep it that long again anyway as there are so many things that I use this product for now. It says store at 21degrees or lower and it got hotter than that in the house this summer.
Also mended the seal on an attack alarm, a fridge handle, plastic mobile phone case.
