Review on Secure Your Vehicle with MONOJOY Faraday 🔒 Key Pouch Fob Protector in Black PU Leather by Ken Lawson

I bought two of these to protect the transponders for the Ford Edge. As expected, the covers block transponder signals and also offer physical protection. They also appear to be durable, although it will take longer to be sure as I've only had them for a few weeks at the time of writing this review. Their main disadvantage is their thickness. You can stack two Ford Edge transponders and they'll be about as thick as one of those cases. Very bulky in my pocket, especially in combination with my key case. Thickness aside, this is one of the best keychain cases I've seen, although my search for a thinner design continues. If the volume doesn't bother you, I would recommend these.
