The difference really is night and day. Amazing!
I have one major issue, though. Their original "Redeem" button was ugly and garish, but it looked like a button. It screams out "click me. CLICK MEEEEEE".
The new "Redeem" button is gorgeous, but it's actually a step backwards in terms of usability. First of all, it doesn't look like a button. Am I supposed to click? Where? Are the little circles also buttons? Speaking of the little circles, they really steal the show. They're so colorful and attractive, that you don't even notice the central circle - and, critically, you don't read the text that says "Redeem". I had to look at the pre-overhaul image to get a reminder of what I was supposed to be doing at this screen.
