"Solar but not heat tolerant."1.5 starson by grillsgt47
Pros: In cooler weather this is a great hands free unit, solar power keeps it charged very well, mounts on windshield, tap it to take a call. Received sound is excellent and plenty loud to be heard throughout the car even at highway speeds.
Cons: , but now in the heat of the summer, the plastic swells enough that the controls don't work and I either can't get it to turn on, or conversly, can't get it to turn off.
Summary: The heat insensitvity is a major issue, which has made the unit unusable the past few weeks this summer and we're having a mild summer with mid to high nineties so far. I would only recommend it for cooler climates.
