It really blocks the signal from your vehicle to your key fob, and cell phone. Surprised the heck out of me. Great value.

### ⭐⭐⭐⭐⭐ A layer of protection for peace of mind.
*by J***S on January 15, 2026*

The bags hold my key fobs or phone, and work exactly as they are supposed to. Normally my car knows when I am in range. When I have my devices in these bags, it doesn't notice me, and so presumably no one else can see my devices either. The bags seem well made and are the right size for my small items.

### ⭐⭐⭐⭐⭐ All kinds of helpful uses.
*by J***R on June 8, 2021*

I like that these bags are large enough for my phone, keys, and my mp3 player as well if I happen to have it on me when we go to the beach. They are waterproof and keep sand out of everything, as well make me feel safer with their signal blocks ng capabilities. I think they'll also work well if we float the river. We also currently have a grandson who throws everything he can get his hands on into the fire... Lol So, I'm thinking these might come in handy around the fire to keep my phone in when it's not physically ON me. If only we had some large enough for the chair cushions we lost to the fire last week.
