This is the coolest windmill and it doesn't take but a little breeze for it to spin. I put it together by myself, took a little time but I did it. I suggest putting it together with it laying down but don't tighten the screws and nuts all the way until completely assembled and standing in upright position. But it is definitely worth it. The red color is very vibrant and its just a welcome joy to my yard. It stands out for sure. Great purchase
