Query: Has the charger been fixed?

I read all of the ratings before I bought the 645. Everyone seemed to have problems with the charger. When I charged my headset I the charger to be very good. I couldn't dislodge the headset by shaking it or tossing it on the seat of my truck while charging. It seated in the charger and was secure. I think Plantronics should change the charge indication to a solid red while charging and switch to a blinking red when the unit is 90% charged, but that is just a suggestion.Sound quality is excellent and volume is great.
