Query: Beware of Jabra products--poor quality control!

Just two days after purchasing the BT125, it quit transmitting while I was talking...still could hear but no one could hear me. Tried everything. Got it to work after turning my Razor off and the Jabra off. Then powered both up. But after 10 minutes the Jabra quit in the middle of my conversation again.I owned the Jabra 200 for three years before it finally fell apart from use. Too bad Jabra now mean Junk.Don't waste your money on Jabra.
