The G903 has to be one of the best gaming mouse Ive ever bought. Not enough that I have a doubt as to did I order the wrong size but definitely noticable. They?re lightweight but sturdy, and don?t look cheap. The fan was very easy to set up. Jealousy was born. I had a plain gray case previously, so now I have something cute & protective. I didn?t know how to wear it but I saw another girl with tied pearls in a knot so I copied! It is easy to assemble, however once you progress in the assembly, the tension can make it a little difficult. But the bike I bought didnt have the usual available spot to install a standard kickstand and the shop owner said you cant install a kickstand on these bikes. And you don?t need to store your headphones in a weird way like the Sony- Sound quality is amazing.
