Caution: satisfaction dissolved to 2x in smoke

We have spent half a year now have to send 2 units back. At first everything was great. After some time the engine runs rough. It immediately follows Barney and smoke we could make out not only with the nose. We have now first no appointed third party. Too bad, because the device is actually ne good thing.

We have really juiced no coconuts and weight training we do in the studio. After the first return we were even more cautious and have hardly exerted pressure. Apples, beetroot and Co were cut previously. We have produced last three weeks regularly good 1 liter of juice once a day. For this purpose, the unit two, three or four times let run for a few seconds.
We are now looking first for another model or hope for an appreciation by the manufacturer.
We are not the only ones with the topic.
