Whatever you do, do not buy this machine
I have owned a Purei9 for a couple of years now and I must say that I think it was a waste of money.
Quite early I send it for service since the function was so far away from promised. But it returned without a comment so I think that there was no mechanical problem with it.
Software upgrade after upgrade but still not even close to perform in level with the price I payed for it or was promised by marketing.
Now I give up and leave it for recycling. Sad, but what to do?
