Pro Vibration feedback
Pro Good value for money
The wired controller is often sold under $40, but feels solid. Being that it is made by Microsoft, there should be little to no compatibility issues out of the box, which is also something to consider when comparing value.
Pro Good availability
You can find it almost everywhere. Easy to find and purchase. Most big box stores carry this item as well as many gaming stores, not to mention a variety of online markets. There should be no issue finding this controller for a good price.
Con Poor D-Pad
The controller has a cheap and imprecise 'swivel'-based D-Pad that rests very high. Poor for any D-Pad uses, and essentially a no-go for fighting games given the competition.
