I bought one last year that only lasted about ~month before it stopped working (I forgot to take the FOB out of the bag and the door still opened).
So then I purchased a different brand that advertised "3 layers", and now that one stopped working after ~2 months.
That had me considering the
GoDark Vault key Fob case. It's double the price of the pouch at $50 ea, getting away from the soft pouch design:
The GoDark Vault - Key Fob Faraday Cage

But before I ordered it, I thought my keeping the keys attached to the FOB while it was in the pouch had possibly contributed to damaging the signal blocking liner.
So the bottom line is, I had an extra unused pouch that I will now test out without the keys attached. I'll keep you posted ...
