After some research I decided for this model, and it has not yet repented.
You put the garlic unpeeled (I remove previously the "root) in the press, presses once (even made my 8 year old niece with no problems) and you're done. So even large amounts quickly go out of hand.
The cleaning is running without any problems. It takes normally not even detergent, special rinses the press simply by hand under running water.
The service I have not had to take, but seems to be very much. I got a few days after receipt of the press an email in which everything necessary state what I would need to know in case of problems with the press.
I highly recommend this press fully. In my opinion, the somewhat higher price is absolutely justified, and to me is to have rather spent a little more money, and for that to be allowed to use a good product.
