Pros: SteelSeries is always a "Pro" as I have used many of their products for many years and have had little problems with them. Also, with this particular mouse I like the fact that the wired option has tabs keeping it from disconnecting during use and that there is an orange blinking warning light for you when turning off your computer which reminds you to turn off the mouse as well once the computer shuts down completely.

Cons: The only "Con" for this particular item is that the battery life is very short, my guess is that when using the "RGB" settings this drains the battery life very quickly which forces you to use the wired option instead of the wireless as intended given this was the purpose of purchasing a wireless option.

Overall Review: "Overall" I am satisfied with my purchase and definitely would recommend this product if you do not mind having to use it while wired not ever using the wireless option as it doesn't seem to keep a charge.

Pros: NONE: No BIOS on Board, rendered useless!

Cons: No BIOS on Board, rendered useless! Seller sold item as "NEW", buyer beware!

Overall Review: Seller is listing boards as "NEW" without having bios! This board is useless!
