O F710 nada mais é que uma versão melhorada do F310, começando pelo gripe(pegada) emborracho, tem motores de vibração, os botões Y,X,A,B são mais altos o que pra mim foi bom e é mais pesado(algumas pessoas pode não gostar), mas não é nada que incomode ainda mais pra que já vem de um controle de xbox one ou ps4. The assembly is really as easy as the videos indicate. The case is really nice - professional quality. The birkiflor is synthetic & immediately super-comfy & clean easier, but begin to look worn after about 8 years as opposed to 20 years! I will say that I originally purchased a size 7 1/2 (down from my usual 8) and they were too loose across the instep. Its fine to be able to move it up (toward your temple) or down (toward your neck), but being able to move it outward or inward would be great. There were some dark spots still on ther grey sides but otherwise, they looked great! I thought Id give these E90 models a shot. Must buy if your looking for serious quality! Richer and warmer than it ever has before.
