These refillable K-cups do what they were advertised to do. I was tired of dumping all the plastic K-cups in the garbage even if the expense wasn't a consideration. I have tried them with several quality coffees but there always seems to be a slight ring of foam around the cup. One word of advice though, clean them almost immediately to make it easier.

Excellent steamer. Easy to clean, does a great job on everything we've cooked so far and it's light and easily handled. A must in every kitchen.
