I got the machine for her birthday. Not that I'm pissed off now on my relatives, as they should also know that this device though einschweißt but produced no real vacuum. After several attempts I gave up, the results are always the same: There is always residual air in the welded. A request to the company Bormann brought nothing, because there was no answer. This is also a kind of communication with customers ... If one speculates with bringing cheap junk on the market, so buy him a lot of customers, must not be surprised if at some point the customers have a negative feeling about this company name and as a result which prefer to buy something expensive. For me, the thing is, unfortunately, now useless rum, and a unit of this company comes to me never more in the kitchen. Big Scout parole ... Jörg Wernicke, Berlin
