The Afterglow remote functions well, has a good weight to it, and has rearranged buttons for enhanced gameplay (+ and – have been moved for better access in shooters and the 1 and 2 have been repositioned for better virtual console play). It also has lights that mean you can see the remote in the dark (they can thankfully be turned off if you want). The remote itself looks cool as well, having a transparent casing so you can see all the circuitry.
There are however two things wrong with the Afterglow remote, one minor and one major thing. The minor thing wrong with it is that any plastic shells that rely on the buttons being in a certain place, will not work with the Afterglow.
THE MAJOR PROBLEM WITH THE AFTERGLOW is that games cannot decide what the battery level of the remote is. In game it will say the battery is low, but if you press the home button and look at the battery level, it can be full. This is not a problem most of the time, but if you in a game that stops in the event of a low battery (like No More Heroes 2: Desperate Struggle), then the game becomes UNPLAYABLE.
The Afterglow remote is a good one to buy for your extra remotes, but think carefully before purchase if you do not have an official Wii remote to turn to if the game you are playing stops when there is a low battery.
