Happy!
Product is easy to install & charge & doubles the time my POC can operate on battery powers alone.

Best price any where.
Great deal on authentic batteries,not knock offs. Only problem was fighting to get back the sales tax Amazon charged. Being a medical device, they are tax free but it took a couple dozen emails to get Amazon to refund my $18.
