I am sorry to hear that you are not having a good experience with this product. I suggest that you take it back to the dealer you bought it from. Then ask them to get it back to me through the proper channels. I have not heard of this problem before. Hopefully another head will solve this problem for you.
Glad to hear that you like the line. Also thanks for the heads up with this. I will look for your head coming back to me so we can see what the problem is.
