Anybody own the Invisio G5 bluetooth headset? I'm looking for some user feedback.

As the title says, I'm looking for some user feedback on the Invisio G5:

Nextlink Invisio G5 Bluetooth Headset - NEXTLINK-G5

This thing is obviously TINY and I love the concept of the portable charging case that allows you to charge the device 5 times without plugging it in. However, bottom line with these devices is that it has to work well, and I can't seem to find many review of it.

So, anybody here use one? Please give me your thoughts on it.

Thanks in advance.
