Solar Panel Self-Recharge Rechargeable Bluetooth V2.1 Speakerphone Handsfree Carkit

Pros: A lot of features. Can pair with 2 phones together at any given time, my guess is that is has been devised for couples using the same car. I never charged it otherwise than by sunlight, even in European wintertime, which is not as bright as one might think. suction cups are usable usb recharging never needed so far.

Cons: Pretty complicated to use in dual-phones-paired mode, but it is ok if you read the manual carefully. must wet suction cups in order to work must pull over while talking because engine noise gets easily picked up by the high-gain microphone. I personally think you shouldn't drive and talk even with handsets.

Other: i do not use it much, because i don't drive that much any more, but it has worked just fine

Pros: Nice product. Easy to use, sound on speaker has good quality, and sound is clear to people in the other side of the call (mic is good also). When you enter in the car, the mobile links quickly and automatically. The rubbers are strong to maintain the device in the glass. Led blinks on different timing and colors being very useful to identify device status. The battery can be charged in usb port too.

Cons: Nothing until now.

Other: Good cost x benefit.
