Solid, well built.

Signal strength, gain, response

One of the worst wireless controllers I've ever played games with. Signal would drop, controller wouldn't be detected, or multiple starts required to detect it. I was sitting two feet away with a clear line of sight to the usb antenna. Just junk. From now on I'll be getting wired.

None

Does not work with Windows 8.1

Do not buy if you have Windows 8.1

Plug and play for most games I've used it for. Has a switch for Xbox 360 layout or custom mapping. Feels a bit heavy, but I now prefer it over a lighter controller. Rumble No connectivity issues

No off switch, you have to take the batteries out. Triggers are on weird angles, takes some getting used to.

Great reliable gamepad.

Solid build. Comfortable for elongated play sessions. Triggers have good resistance and tactile feedback.

Intermittency issues. This seems to be a recurring problem among a number of owners. If you look it up on the logitech support forums there hasn't been a concrete fix in over 4 years. I notice the problem on rare occasions where I would lose control for about 1-5 seconds. The frequency of said problem would be around 11 times during my 33 hours playing dark souls. It's happened at least once with other games as well.

It's perfect when it's working. Which is 99% of the time. The games I use it for, however, really hurt you the during that 1%.

Strong build. Smooth, tactile, button feel. Easy to configure in Windows and Windows 8 (plug it in and go). Excellent range. Excellent battery life.

Slightly heavy. Vibrate function is silly, and mostly useless.

I can't imagine doing any better for $50. Wireless, great range, great button and stick feel, reliable, and amazing battery life. You can't go wrong.

AWESOME Linux support Good weight (A bit heavy but that's how i like em) Stiff buttons but doesn't take much to actuate them

NONE

Bought this to play in Steam's Big Picture Mode, plugged it into my linux machine (Arch & Mint separate installs) and BAMMM...shows right up in lsusb worked out of the box the second i plugged it in!
