I've just had my second Hello 016T charger fail....that's two failed chargers in two months!!! I have my Riva510 SE as a backup. I assume that I can't charge my Hello 016 batteries on the Riva charger, as the battery size of the two is not the same? I'm rather frustrated with this particular charger, as surely, I can't have had two faulty chargers. Looks like I'll be buying another PV soon, and I have no idea what to get. I'm tempted to just get another Riva. Does anyone else experience equipment failure often, as if this is the norm, it's going to get rather expensive!
