Have any of you AT&T wireless customers tried one of these yet?

Good, bad, neither?

A guy I work with has one; says it works well. He’s in a valley and has no cell coverage at home.

AT&T finally turned up the tower near by my house, so I’ve got 5 bars. Must be why I got an email offer for a free micro-cell this week!

My father in law put one in his house because he is in a dead spot. I have a customer that uses a bunch of iPhones in a base of a building so they put one in. They seem to be great with one exception. If you walk away from the range of the Micro Cell it will drop your call. It goes through the internet so its a seperate call than calling on the Edge or 3G network, so it can't switch between the two.

I see a lot of this in NYC, they work well with the above exception

I can understand the hand off between the LAN network and cellular. That's OK IMO.
I've used the Vonage App for several years on the iphone, but can't receive calls.

I'm looking to get one for home use, as where we live has very poor AT&T cell service.

Got one for the house, so far - so good.
Works great!
