"Great product!"4.5 starson by powered
Pros: excellent response, excellent battery life, great build quality
Cons: slightly heavier than regular ps2 controller
Summary: This is an excellent product. I've had it for around 6 months and haven't experienced anything negative yet. The controller is comfortable and the layout of the keys are right on. I turned the vibration feedback off and have not yet needed to replace the batteries. The response is instantaneous; no notice of any lag. I would highly recommend this product and this manufacturer. I have not had one bad experience with Logitech yet.
