Even Better for BMS play
This is the most Machined, solid controller. Its USB so it has more uses than just DJ max(ie BMS starter pack), its also "triplemapped" so you don't run into a problem where you max out on simotaneous keys pressed.
the buttons are spring loaded so you can hit 16ths with little effort. however the software is not included you must go here to get the software for free http://www.gammac.co.kr/gammac/new_gm/main.php click in the upper right where it says "triplemapper" enjoy, this controller turns heads and grabs attention. however it is noisey...

Awesome controller!!!
Being an avid IIDX for some time now, this controller is the best thing to have to play DJMAX. The truntable is nice and the button don't stick like the Konami IIDX KOC. And anyone who wrote a bad review for this, go pick up a KOC and IIDX and start playing, because It's so obvious that you've never played IIDX before. I give this 10 out of 10. If you love IIDX, you love DJMAX, Pick up this controller. Highly recommended.

you'll hate it once you get it
well, at first it seems it's really cool to have one, but after you get one, you'l wish that you never would. thread lightly, it's a 'want' item and not a 'need' item to play dj max

Oh my god!!!!!
I buy this item when it full price.....

Quick responses for quick fingers!
The Muse-On controller for DJ Max Trilogy is the perfect peripheral for the perfect game!

Small enough to sit on your lap, with non slip rubber strips on the bottom it won't be moving around even during the craziest of Super Crazy tracks.

The only improvement I would make to this would be easier to press buttons. While I have had no problems at all, the keys aren't as easy to hit as (for eg) a Beatmania IIDX Arcade controller.

Still, a far cry from a keyboard - this controller has helped me improved IMMENSELY - I can now compete online with confidence!
