New in box, never opened or used. It costs $300 + tax from the Sprint Booster store. I'll sell for $250 shipped. It's the version for the R231, but may be able to work with other cars as well - there's a fitment link on the sprint booster site, but you have to select the car and then it tells you the version, instead of having a compatibility list for the version.
It's the latest version (SBME0013S - Sprint Booster Select V3). I can provide pictures if wanted, but it looks pretty much just like the box shown at this link.
