At a bit more then the Amazon version, I can also vouch for Fox Run. Another china made product at half the matfer price, with a lower temp rating.
I've been using one for 5 years or so now, and while it's darkened considerably (went from transparent to a light-mid brown) it's still just a flexible as it was, with no cracks developing and beautifully nonstick. The fit and finish on it is fantastic, no exposed fiber, edges have not degraded since it was purchased at all.
Considering these mats are meant for cookie baking/candy making, I don't see why a 500F+ range is needed unless you want to try and use it as a replacement for parchment paper for bread baking which seems ill-advised.
While I love Matfers pans, I'll be purchasing two additional fox runs instead of this. They get the job I need done and the quality has proven itself to me, I'm sure the Amazon version would be just fine as well, just remember no dishwasher, keep it out of the sink so it doesn't accidentally meet the sharp end of a knife while dishes are piled up on it, don't put weight on top of it while it's folded and don't cut stuff on it and I'm sure you'll have no problems.
Edit: 10/25/2018 1036 So I looked it up and apparently there's an alternative to parchment called the SilPain, which is about the same price of this mat and designed to be a reusable option for bread baking. Supposed to give good results, but it has a lower temperature then you may need if you tend to crank your oven to get decent oven spring. If matfer used whatever silicone they used on this mat to make a textured bread baking mat I would be all over it.
