Summary: I used both wireless and corded versions. they are both excellent gamepads. they feel good in your hand. wireless one is a bit heavier because of the batteries, but you'll like it better when you get used to it. it has excellent range. it goes to standby after 5 min if you don't use it, and saves battery. led light lets you know when the battery is weak. the only downside is that the vibration doesn't work with every game, especially the EA sports games. thats the only reason i didnt give 5 stars. also you don't need the software if you are using windows XP, you cannot calibrate it after you install the software that came with it.

Summary: Well this is the 4th Logitech wireless (Wireless keyboard/mouse combo-MX DUO,LX500,PS2 wireless controller and this controller for the PC) product I have purchased in the course of a few months and I continue to be very pleased with their products.I gave Logitech a shot many years ago with the purchase of a marble mouse and wasn't too impressed but their wireless products are a different story altogether.The battery life still continues to amaze me.I am not too sure of the battey life rating of this controller BUT I imagine it is on par with the one for the PS2...which since purchasing has NEVER needed new batteries in about roughly 4 months not bad on just a couple of AA batteries (battery life is less with rumble feature activated..don't like rumble myself so keep it off..but even with rumble battery life is something like 50+ hours...amazing..with rumble off..like 70+ plus hours).Setup of this controller is pretty straight forward which starts with installing the software THEN plugging in the controller when prompted to do so (sometimes when installing USB devices,like printers, follow the order of operations and install the software first...trust me saves many a headache later).Actually with this controller tossed the install CD and went directly to the website for updated software/drivers as with almost every computer product always feel its best to start out with the newest software/drivers available.The USB reciever chord is also pretty long so you don't have to worry about it not reaching the computer.The only games I have used it on are old school video system emulators (NES,SNES,etc.) and its works w/o a hitch.The ONLY very small thing I don't like about this controller is the location of the rumble button and the mode button...they should have switched it around with the buttons above it (so use to the SELECT and START buttons being located where the rumble and mode buttons are..kinda messing me up) but like I said very small problem.Not sure if I mentioned it but the build of the controller is very nice.It feels like if it was to be dropped it wouldn't shatter into hundreds of pieces...feels like it can take a beating,durable.This is a really nice controller that doesnt keep you pinned to the small computer screen.Also just got a new video card with an S-Video output feature so got that outputting the desktop to my TV coupled with the wireless controller it feels like owning a few new video game systems when using full screen mode...sweet setup.If you have been eyeballing this controller and wondering if you should get it or not trust me get it you will be very happy with it as I have never been a BIG fan of wireless products BUT they have really improved the over the years.

Summary: The Logitech Rumblepad 2 is awesome. Its wireless with no lag, and fits very nicely in the hands. Being wireless, I can lay down on the bed and play games all day long. I liked this gamepad so much I'm going to purchase another incase a friend comes over.
