Pros: The keyboard works very well. It's very sturdy and the keys are extremely accurate. The rubber is a nice feature.

Cons: This product has horrible reviews, which delayed my decision to purchase it. I know, that's a pretty bad con. Watch out for it.

Overall Review: Let me begin with, I play rhythm games using a computer keyboard. I play for hours, nonstop, and I don't hold back. This keyboard has to be the best one I've used when it comes to playing rhythm games. The reviews on this site are pretty misleading. First of all, 'the rubber comes off'. I can only imagine this happening if your nails DIG into the rubber and TEAR it off. I bash on four keys 6+ hours a day and I see no wear. Second, 'the blue light is dim'. It's pretty bright to me, and the sun is lighting up my room. I can only see it being dim if you are extremely short and are looking at it from an angle. Third, 'non-responsive keys/multiple hits for one tap/typing glitches'. I would be able to tell if this were true RIGHT AWAY. My game depends on accuracy. This is NOT a hardware issue. This is caused by the software some of you decided to install. There are other free ones available that work better. This is a video of me playing, need I say more? http://youtu.be/c5wbzNM
