Review on Calisto P820 Mobile Discontinued Manufacturer by Diana Comeford

Not impressed at all. Sound quality is pretty good, but that's where the good ends. The 1 button on my device works about 1 in 20 times I press it, the device's response when dialing is terrible and it regularly misses keystrokes, pairing with the phone is easy, but the sound quality isn't much better. than the phone's built-in speaker. One SUPER annoying thing is that I can't get it to work with most USB power adapters I have. I was hoping this speakerphone could use it with USB portable power. The power supply that I carry in my bag (MyCharge 6000XT) to be able to use the hands-free system on the go. My power supply has both 1.1A and 2.5A outputs, but neither will power the device. keeps turning it on when I connect it to my Macbook Pro. This means I have to take my computer out every time I want to use it. This goes into my recycle bin.
