K2 review

I ordered a second K2 because of the size and positive experience with the charger. Unfortunately there was a problem with the shipment and I never received the unit. It took a few days to get a response from the store but they verified that there was a shipment problem and a new one was sent to me in a couple of days. Overall a positive experience with the charger and with customer support!
