Query: It's a cool little device for the price!

For the most part it's a great little device. It's certainly nice to be able to walk around hands free especially during those long conference calls. And it works great with my BlackBerry! It's not so great when you don't already have it turned on and synced up with your device. Takes me forever to turn it on, sync it and stick it over my ear. Just keep it turned on so you're ready to take the call!
