i really hate the fh.com forum search feature. it rarely works for me even if i put more words than necessary. so yes, i did try the search feature several times and it came up with nothing at all or told me to enter more words. i'm asking somebody, who has better luck than i did, to post a few links to threads about the eye glass insert or to the altec website. thanks. sorry to vent about the search feature but it never works for me!!
