I bought the platinum B70 and it immediately stopped working correctly. The thing repeatedly turned off for no reason whatsoever and if I had the patience to wait for it to work and the machine decided to randomly cooperate it would probably take 15 minutes to make a single cup of coffee. I would start it, it would make some noise like it was working and then shut off. Restart it...shut off. Restart it...shut off. Unplug it and start over and sometimes it would work. So I sent it back for an exchange and the new one I received did the same thing so I sent it back again but this time I asked for a refund. It turns out you get only an 80% refund even though it is faulty and doesn't work right and even though I sent it within 30 days. So I am out $31.00. Then I bought a standard model at Costco. It shuts off by itself too. So I'm 0 for 3 and I'm very surprised this hasn't happened to a lot more people. I doubt if 0 for 3 is just bad luck! Don't buy it!
