Pros: Easy to install and good manual instruction. Great performance for the money well spent. It uses some Asus application programs.

Cons: Could not figure out where to plug the 2 pins male of the power switch and reset switch to motherboard. Since this mobo comes with these switches incorporated in to it with no female pins. Manual instruction does not tell where these pins go in to. I did contact Asrock and it seems that they don't have a technical support department. Asrock suggested to contact back to the retailer.

Overall Review: Excellent performance.

Pros: Good design, very easy and simple to use, reasonable price if promo code is available.

Cons: Way to much steam water dripping down from the top of breather hole during each cooking (got tired of cleaning it after each use), no internal steam basket to cook extra stuff and the buttons feel like about to pop if you keep pressing for a long time.

Overall Review: I might kept it if the unit doesn't leak steam water during each cooking.

Pros: Relatively fast reading and easy to install.

Cons: Audible fast fan noise like when reading a cd or dvd. Not annoyed by it.

Overall Review: Good optical device.

Pros: it performs as describe and nice heat dissipation capability.

Cons: It is touching the side of the cpu fan Master cooler hyper 212+.

Overall Review: Excellent performance with no problem.

Pros: Great cooling capability and nice 4 led red lights.

Cons: Fan squeaks every time when first starting or restarting the computer. It is very audible and annoying at times. It is like switching a manual transmission into a wrong gear. Very poor manual instructions. It only has a few pages of instructions in English.

Overall Review: Easy to install.
