The faraday bags effectively blocks the signals from the key fobs. My only negative was the velcro fastening method requires two "folds" of the bag top which makes the folded top extra bulky.
Great product, gave as a gift and delivery was very fast.
Works as advertised
Great product for ipod nano shuffle
I love this little pouch, it works very effectively and has made finding my keys easier too. Definitely recommend this item and compared to others that I've seen, this is a great size.
Totally satisfied. Using everyday. Also there are enough place for id and couple cards. And that thing doing it's job properly. Blocking all signals.
