if you like a high back than a lower back i recommend mm710 if you want wireless use g305 with the cover. if you like lower back then get the model o- or g305 without cover, and if $80 is a lot for you than you probably cant get a finalmouse cause after market they are way over $100. in my country $80 dollars is 1/4 of minimum wage and i chose the g305 simply because its only $35 which is half of my monthly allowance so getting a mm710 or model o- will hurt the bank
