"Playstation 2 Cordless Action Controller"
As said before many many many times, this controller beats anything out there for the PS2 system. The first one I had played like a charm but I remember dropping it one good time and it kind of stuck in certain ways in various games. Anyway, I decided to buy another one two years later and I must say that it has shined again! The sensitive reaction when I play various racing games or adventure games like ICO or Shadow of the Colossus, or FF X2 and Fatal Frame's 1-3, has been past my expectations. The biggest thing that I really love about this controller is that I can be laying in my bed with the control under my covers and it will still respond to my commands with no effort. I can't do that with my TV control, my LG DVD recorder controller , nor the controller to my Onkyo stereo system! There is just one thing you have to make sure of, and that is to hold the controller carefully because it's surface is slick. I haven't broken any of the sticks because there is no need to damage them that bad.
This is a near flawless controller. If only it had a button to cut off the system, I'd pay double for it with no problem! Kudos to Logitech for the best controller in the Playstation lineup EVER!

"Best Controlled Ever!"
This cordless controller is awesome! Not only was it easy to set up, but it has always been able to wirelessly transmit between it and the PS2 console. It is comfortable in your hands. It will work anywhere in a room, even you objects in-between you! This is a great controller!

"Pleasantly Surprised"
I was hoping for a decent controller, but I was greatly mistaken, this is almost identical to using my standard PS2 controllers. Controller has great battery life, is very responsive, and feels solid in my hands. I would definitely recommend this controller to anyone looking for a wireless PS2 controller. I wish I had bought mine years ago. If you are in the market for a wireless PS2 controller, look no further.

"Wireless Logitech products need I say more?"
Logitech products have always been reliable and long lasting for me. I love how this controller is wireless I have so much stuff in my room so I try to avoid wired products as much as possible. This things still works great and gets a lot of hours put on it. If you still have a ps2 consider getting one of these.

"Nice wireless controller"
This is a great product. I haven't experienced any connection/lag problems, the sticks and buttons feel nice and responsive, and of course it's wonderful not being tethered to the PS2 while I play.

My only complaint with this controller is that it's not quite as comfortable in the hands as the DualShock 2. In games that don't use the trigger buttons often, I like to rest my index fingers behind the controller body in the space under the triggers. On this controller, that empty space doesn't exist because it's occupied by the battery compartment. I have to rest my index fingers on the triggers at all times, which is probably how a lot of people hold the controller anyway, but it feels a bit awkward to me.

Aside from that small issue, I heartily recommend this controller to anyone with a PS2.
