XTAR Over 4 Slim 2-bay charger

I've started talking to XTAR a good bit more lately, and after my last XTAR review (of the VC2 Plus Master), this just released XTAR charger showed up in the mail one day.  This is the XTAR Over 4 Slim.  "Over 4" is an indication of performance - this unit is rated for charing at FOUR POINT ONE amps!!
