At last I had found a pad machine that looks a bit extraordinary and no negative reviews has (leaking water, plastic taste, etc.). However, to me the differences between the variants were not very clear, especially since the prices also change constantly. So I sent an email to the manufacturer, and was answered nice the next day: The HK11W and HK11M are identical and differ only in the color (white or metallic). The HK20 is the premium model and has an LCD display. In the mail then stood still, that there are these machines even at a large electronics store chain. OK, you want him some day enter the regional trade again ne chance - so I've since looked into this. Well, as a HK10 on the shelf, so the previous model. Hm, so clearly can not have a business all types on offer, but it shows up again clearly the advantages of online shopping. So a comprehensive overview of the market you can get only here to give. OK, so I ordered the HK20. In the box were also 2 pretty cups and 3 tasting packages of pads. Since it is now my first pad machine, I have no comparison to other types. I can only say that everything is working fine and the coffee is delicious. And he's really hot, even with cold cups, exactly ready to drink. Tea I have not tried it yet, but it's a separate holder for Teepads here. So chic, super coffee, thus 5 points.
