Pros Works completely solar (no need to plug in). It just sits there and works exactly as it should. Nice and loud. It is far superior to my Garmin GPS with bluetooth.
Cons Paring was easy, but I forgot how to do it when I went to connect a different handset.
It turns off after a while. If the battery was fully charged, I wish it would just stay on all the time.
Summary If you have any issues with another method, either using your cellphone's speaker phone, or using a multi-feature device (like a GPS to act as a speakerphone), don't give up. This device is on the expensive side at around $70 as it is a single-function device. However, It is well worth the cost and I highly recommended this device.
