I'm very happy with the orka brand silicone tipped tongs I got back around 2008. I think they may be the same as the ones made by mastrad now, but I can't be sure without seeing them in person.
The set I have has held up extremely well over the years, and still looks and works like new.
This feels like the wrong place to shout out plastic IKEA utensils, but I have had a FULLÄNDAD ladle and pasta spoon for years now and they show no signs of wear.
They are made of a single piece of smooth plastic, so there is nowhere for gunk or water to get trapped, and they are heat proof up to around 400*F.
The worst things I have found for the longevity of kitchen utensils are seams, and hollow handles which trap water, and having non heat proof handles because the end that's not supposed to touch the pan will at some point touch the pan.
