Received the ZOMM, gave it a try, and it's not for me. It's too much trouble. Keeping it charged is a pain, and my phone will not re-pair with it automatically, as it does with my car bluetooth. As I think someone pointed out above, it's a complicated solution to a simple problem. If the ZOMM didn't need to be "managed," it would be a whole lot easier. As it is, it's just one more thing to keep track of.
If anyone would like my ZOMM, I'll sell it for $15 + postage (so like $20), and I am open to offers.
