Firstly, I can't believe it is a portable device and how convenient that is. But that would be pretty useless if the battery didn't last. So I am extremely impressed with how long the battery last. The WhatsApp help desk is very quick and efficient as well. I haven't even been able to put the strengh up past 4 bars yet. Its amazing. Also the two output can be set to different strengths. I have to admit, I thought that it was a trick or something that the sales guy had some other unit, but my unit is is the same and works absolutely amazingly. I can definitely recommend this device and im looking forward to pain relief on many levels...
