My first impression upon receiving this product was that it wasn't quite as cool as the picture. It does light up blue, which is an option to turn on/off, helpful since it runs on batteries. And there is liquid, but only in the hand grip parts. It's just not as cool as you'd think it should be.
Anyway, within an hour of operation(playing Singstar on PS2), mid song, the pause screen popped up and couldn't be fixed. If we pushed buttons, it would go away for a spit second and pop right back up. My computer nerd boyfriend could figure out how to easily fix it. He said maybe it was interference from being wireless. I returned it the next day and bought a plain blue one from Vstock that works like a champ(and is cheaper).
My vote, don't bother with this one.
