Review on MONOJOY Faraday Box for Key Fob, Key Fob Protector, Signal 🔒 Blocker - Car Key Fob & Cell Phone RF Blocker, RFID Book Box by Adam Whittaker

Product works exactly as advertised. It's efficient and invisible. I've tested it with text messages and calls from friends and co-workers and it's blocked all signals I've sent it so far. Bluetooth and WLAN are also no problem for him. The product itself looks great, is made of good materials and will last a while. A copy of the handwritten note from the owners of the online store that sells this on Revain was a very touching and nice touch. My only suggestion to them is to either give the "book" a title or let the customer choose one. design it yourself and engrave it on the spine and cover.
