Bests & Worsts Reviews from Amazon

I was so excited about this product but it is totally disappointment. I just bought it last week and on Sunday it stopped working properly. It is filling the cups half and turning off itself directly. I did all the troubleshooting steps and nothing has changed. I would like to replace it but now they just offer refund and increased the price by $20. I would not expect that from a Keurig product. Keurig did a replacement and the second one was the same. I returned it and ordered again and this have been working properly for three weeks.
