I have sent some e-mails, and a PM with no response. Are you having problems with your e-mail? I want to know if you sent out a head last Friday as you indicated you would. I have removed the head from the trimmer, it is too frustrating in it's present state to continue to use. Please let me know the status of the head. Also the design on the bottom cover cap seems to be lacking in my opinion. The plastic piece does not seem to lock well and falls off and vanishes far to easy.
