"Needs more heat tolerance"3.0 starson by pjhenry1216
Pros: For a third of the year, this thing would be pretty awesome. Fall, Winter, and Spring. Depending on how often you talk in the car, you may never have to take the thing out of the holster to charge it.
Cons: Not too heat tolerant. Left it in the window during summer and it appears the inner bag of coolant expands too much. The buttons get stuck pressed against the board inside, so either you can't hit talk or you can't hit power (or both).
Summary: Pretty cool. Don't leave it in the window on hot summer days or it may never return to normal working condition physically. If buttons get stuck, try throwing it in the freezer before popping it open. That may actually fix the symptom as opposed to opening it to try to unstick the buttons and finding you can't fit it back together again 'cause of the coolant bag (or whatever it is).
