I had a mixed experience with Beijing casc energine wind turbine co., ltd. Overall, the quality of their products is average. The customer service was decent, but nothing exceptional. I expected better performance from their wind turbines, considering the price. However, their website is user-friendly and provides useful information about their products and services. In conclusion, there is room for improvement, but it's an okay company.
