I am happy with the purchase.
However it is not 500w, but rather 200w.
The model is even named 200, so I would have appreciated if the listing was ”correct”.. on that note it will actually produce around 250w!
Upon delivery the main bearings were damaged, but it was solved with vevors support and i am happy.
I would recommend anyone to open the housing and clean the slipring surface, install a moisture descant inside, and apply a liberal amount of vaseline to the o-ring &mounting surface. That will prolong the life of your turbine.
Also went over all the blades with sandpaper to remove any imperfections from the moulding, checked the weight of all blades and ended up having no more than 0,5 grams difference!
