Installation is straightforward - USB receiver into the PS3 plug, press PS button on the controller and you're everything.
The handling is perfectly side. The controller is great in the hand and is modeled after the original in form. The grooves on the sides provide more bonding, so that the controller also non-exposed even after long use in the hand.
Battery life is very good. After playing more than 20 hours, the controller is still loaded to 80%.
The only drawback: The controller can not turn on the PS3, because it only works with the USB receiver. This was clear from the outset, since it is only about a third party.
