Not cheap. I bought it a year ago from Sri Computer clearance also RM300. It's not bad, even have 2usb port extension to plug your mouse. Not to mention the palm rest is a bonus.

About a month later, I went to a warehouse sale and bought CM Stealth for RM200. I decided to use this one instead since it had mx red which is softer. Was planning to use the trigger for my office work but laptop was stolen during a break in. Still haven't bought a replacement.

My bad... recheck my box and indeed it was without Z.

Why don't you returned it? I would really hate it when it become sticky. Mine was in perfect condition despite being an older product.
