I would have given it a five star if the instruction told you how to move the adjustment knob. I learned this from reading reviews. You need to lift the knob half way up to go to the next setting. I almost ripped the knob off trying to get to the next setting until I read the review. I hope this helps someone like the review helped me. Good product.
