Takes batteries they never work the red one worked for about 2 weeks and the blue one never worked at all pretty munch junk and a waste of money.

These work great and for the price cannot beat it

These work great, until the battery starts running down, then it's nice to be able to switch to the other & continue the game.

1 works great, the other one the analog on the left side doesn't work, if you try to go a certain way it'll be either slow or won't go at all after a couple of days

So far so good these are working great for our PlayStation 2

The blue one worked well for perhaps a few day....then failed permanently.
