The bag works well! It hid my fobs signal as long as I had it in the bag. The only thing that I have a problem with is the key chain on the inside and the clip on the outside. I had this hanging on my keychain for approximately 3 days and both tore from the bag inside and out. I started using the other and I could see that the same was about to happen to the second bag. Not sure it was worth it to buy.

I understand the need for the case but after using one for a few months I find it awkward and cumbersome. It’s big when you add keys and the dangling fob. It can’t fit in your pocket and it barely fits in your purse. My husband refused to use it. I wouldn’t buy it again. If I lived in a high crime area maybe.
