Works exactly as advertised!
I'm from india and i've decided to order this product, firstly the shipping was pretty fast! in airmail, i got it exactly in 9 days!
I basically purchased this to use my Guitar Hero wireless ps2 controller to play FretsOnFire, and that's exactly what this baby does! no hassles no problems just plug and play! This is one amazing product, if you're looking for a ps2-to-pc adapter, look NO further! :D

Works fantastically with an HRAP2
I use this with my Hori Real Arcade Pro 2 SA and have no noticeable lag. Comes with drivers for WINDOWS VISTA regardless of what the product description says! I use it with MAME on TinyXP Rev 09 and it's the best PS2 USB adapter I own by far.

Finally an adapter that works perfect for Stepmania!
I have had many headaches troubleshooting adapters off Ebay to only find out there is the dreaded joystick axis problem. I picked this adapter up after doing some serious research and feel like I hit the jackpot. It works perfect with Stepmania! If you're tired of throwing away your cash on hit or miss adapters try this one. By the way I'm running XP but it's suppose to work on Vista, 2000, ME, and 9X.

This works, what else can you ask for?
Tried this out and it worked perfectly for me. games like Megaman X5, Devil may cry 4 are working perfectly with this adapter. it is very fast as well, there is no delay. the drivers installed fine on XP.

Fine on PC (Not on PS3)
Though it uses the USB interface, the Super Joy Box 3 Pro does NOT work correctly with the PS3, specifically with SplitFish's EdgeFX controller. (Only a couple of buttons work, no mouse, no analog.) On the PC, drivers don't seem to install correctly when checking Device Manager. There's also hanging and minor difficulties configuring with Vista's Game Controller properties. Eventually - with patience and configuration tweaks - controllers seem to work well enough. (Vista SP1 32-bit.)
