Decisive for the writing of this review: I wear the Tracker mostly waistband of my panties and unnoticed all my best best wives has put the underpants as usual with other things out of the laundry basket in the washing machine and then into the dryer.
As expected, the unit was completely dead. It was then two days on my desk and just like that, I did it then again connected to the PC. As the device is charged suddenly and now it works perfectly again. In all my many years of experience with electric stuff that's never happened to me.
Congratulations to the manufacturer.
