I received a silicone 'oven mitt', aka the 'crocodile' a couple of Christmases ago. It is fabulous. It doesn't fit over the whole hand, but it's enough to pull out a baking tray without any dramas. I've also got a bowl scraper - brilliant for big mixing bowls as it gets out every little bit of mixture.
Silicone whisks are great for making sauce/gravy in non-stick pots. No lumps and no scratches on the non-stick.
I also have a couple of silicone baking tins. They work very well, the only drawback is they need to sit on a cookie tray in the oven. But cakes don't stick to them with the tiniest bit of oil spray, it's very easy to peel them off the cakes, and they wash easily.
The silicone pot stands/trivets I have are very handy for everyday use too - my stove top is induction, and putting metal trays on it causes an alarm to sound, so I put the silicone pads on the stove top, and put the trays on them. No alarms, no scratches or damage to the stove top.
