Hi, The Holux 236 arrived today, 3 days after I placed the order. The mPower should arrive by week's end, and I hope to get up and running immediately or shortly thereafter. The manual didn't apparently identify the charging time for the battery, but I'm assuming about two hours. When I turned on the unit, a light came on so there was some juice already in the battery. I tested turning the unit on and off. If one is careful, there seems to be a click that one can feel when using the switch. While an audible tone would be nice, I don't mind jumping into the GPS menu to verify the status of the receiver. Boy, this thing is small and I hear it looks quite good. But the proof is in the performance which I hope to check out by week's end. Best Regards, Les
