We regret that we are no longer selling Exmok (aka Exmork, aka Huamin Windpower) generators. The quality of the wind turbine and electrical equipment that we have been testing did not meet our standards. Fortunately, no retail customers have been stuck with substandard products.
Things are changing quickly in the medium size wind turbine business. Companies are popping up and disappearing at a great rate. The quality of the equipment is improving, and we are confident that it won't be long until there are turbines available that will give years of trouble free service.
Meanwhile, DO NOT BUY ANY WIND TURBINE WITHOUT FIRST SEEING ONE OPERATE. Ask for proof that it actually produces the amount of electricity claimed, and make sure that it will automatically shut down in high winds.
