TICONN Faraday Box for Car Keys, Key Fob Protector, Signal Blocking Pouch, Universal, Carbon Fiber

I've been wanting to get one of these boxes for a while, but I wasn't sure if they'd work. Well luckily this one does. I put my husband's cell phone in it, closed the box and when I tried to call it, it blocked the signal. It went straight to voicemail. Several key fobs will fit in here and average size phones as well. This box will give me peace of mind knowing thieves can't steal my vehicle by copying the car signal from my key fob.

Every day thieves and scammers find new ways to disable or bypass security measures. This box protects from RFID %26 car/alarm fob scanning and 100% blocks cell phone signals. I tested immediately placing all keys and phone in box; closed lid securely and called phone. Just as it's supposed to the phone didn't ring and call went straight to voice mail. THIS BOX WORKS and works well! It's very well made-see my pics. The box and lid are well designed and assembled of signal blocking materials. It seats itself flush and tight from the inside out upon closing it securely. The additional closure clip insures it stays tightly closed should it be bumped. The seller's description is 100% accurate including measurements. Everybody should have at least one Faraday box at home or office. You just don't know who may be doing what until it's way too late. This box makes it impossible for would-be thieves to scan fob controlled devices and cell phones. Highly recommend.
