Review on ZENLET Ingenious Wallet BLACK Blocking Men's Accessories in Wallets, Card Cases & Money Organizers by Rudolph Mceachern

It doesn't work as advertised - card panning is extremely erratic. I've tried everything. I've watched all of their tutorial videos to no avail. The fact is, the mechanism is too simple to do what it claims to do. 5 cards loaded - Debit, Amex, etc. 90% of the time at least 2 cards on the back are unblown. It also turned out that it usually takes two movements to open. The fact that they have help videos on their YouTube channel is all you need to know.
