I tell ya, i have tried several times to give them the benefit of the doubt, but man, its like a money pit. Buy the unit, buy the battery, replace the wet side or parts of it every 12-18 months, stalling, falling off the wall. And now, the power supply has stopped working. I think im about to give up and sell. I know they are new, but man, they just dont come close to the performance of my streams (they dont stay working!). Anyhow, when you use the connector how do you set the speed?? Does it automatically dropped the stream to the lowest power draw? I dont want it to keep blasting away at full power!
