This is a fantastic little windmill for the price. Instructions are a little bit difficult to read in English, but the main points stand out.
Shipping was fast, taking about 4 days.
I mounted the windmill on a 30 ft Rohn tower with three 75 ft %236 cables leading into my small greenhouse with 24vdc setup.
One great design feature that the company does not point out is the fact that the vertical pivot contains slip rings so the wires exiting the base never become tangled with the tower leads.
My weather station indicated we had 60 mph gusts, and the windmill worked as designed.
After a little time and testing I may change out to a larger wattage windmill produced by this company.
My overall rating is A !
