I was a big supporter of the Proven wind turbine in the 1990s. It’s built like a tank in contrast to so many flimsy products in the small wind world. But my enthusiasm for the company waned gradually as I witnessed their exaggerated claims and heard from their many unhappy customers (during lengthy development of new products). In recent years they got a big cash injection and became even more arrogant. I can’t feel much sympathy for the company management, but I am sorry for the workers, the dealers, and even more so for the customers, who have already suffered far too much.
