Ease of use
Operation is simple -- just pop the cup in and press the brewer's one button. Fifty seconds later, you'll have a steaming hot cup of joe.

Some cups left behind
Only the cup on the right will work in the K500. The Keurig-branded cup in the middle was produced before January 2014 and lacks the proper label to pass Keurig 2.0's scanner.

Tsk tsk
Try and use a bargain brand or an outdated K-Cup in the K500, and you'll see an error message.
