Query: JUNK

Absolute JUNK. Never worked, tried all sorts of batteries, all types of card (needs poker cards but they didn't work either). Called customer service for Bicycle and got nowhere. DO NOT WASTE YOUR MONEY. I was so embarrassed giving this to a friend of mine in his 80's and it not working. Don't bother purchasing this, no matter what the other reviewers say.
