    Material and snap is good. Doesn't accommodate items besides FOB properly. Can't use it

    Flexible Faraday Key Fob Guard

    Great Product. Highly recommended!!!

    Effective portable protection

    It took a while to get used to at first as the instructions weren’t as clear as they could be with putting the strap around to secure the seal. It also takes a while to break in, in order for it to be a smooth and seamless process. But, like I said, once you learn how to use it, it’s a cool and convenient way to protect your key fob from virtual threats.

    Excellent product. A must have for every female and child in my family

    It works

    Seems like a good product. Confused as to the use of the elastic cord on the inside and the clip (which is very difficult to access)

    Key fob guards

    I guess they work the. Way they’re supposed to. Only way to know is to leave the guard off and have some one steal the car, which I am trying to prevent. It’s a little inconvenient to hav not take them out of the envelope to get into the car, but will be easier the longer I have them.
