I have one. I recently moved to an area with very poor AT&T coverage. I am under contract with AT&T, and I wasn't pleased with the prospect of having to go outside every time I wanted to make or receive a phone call from my house, so this seemed good for me.

I bought one for $150 (not $250). It works, but not very well. On some calls I get fairly severe audio distortion that makes it hard to understand people. I'm not sure how to fix this yet. Still, though, it's better than not being able to make or receive any phone calls at home.

Data usage isn't an issue because I have wifi, and call time isn't an issue because I never get close to my limit anyway.

$150 is probably more than the early termination fee on your AT&T contract, after proration.
