I purchased these two Save and Brew Cups while they were pre-order status. I recieved them within a few days and was anxious to try them out. When I got them, I lined them up side by side with the Ecobrew cups and for the most part, they are identical right down to lettering stamped into the top of the lids. I brewed a coffee using both and the result was identical. No leaks, lid closes tight and my Keurig has no problem with these cups. Definetly worth the $$ saved vs the Ecobrew cups. As mentioned, if I put them in the same drawer together, I wouldn't be able to tell which is which.
