The Winebaa was a promissing device and David sounded a serious business Partner. We bought 30 Winebaas and tried them, and in communication with David addapted them but it just did not work. Our sheep learned within a half a day how to trick the WineBaa and ate the grapes. The just tipped it in the air and could eat what ever the wanted. So I decided to send them back and David told me that he would give a total refund. When I asked more specific who was going to pay the return from Portugal to Australia I did not anymore get an answer from him. He just avaporated from the internet and did not answer his mail. I pais in total €800.00 and the Winebaa's are laying in a box. For someone who wants I have made videos which prove that they just do not work.
