Logitech MX518 was good.sorry for Hijacking the thread, I'm looking for a mouse which is bigger than average and a bit on the heavy side as it gives me more control. Previously used Logitech MX518 which I liked but is now not working correctly.
i would suggest to look at Logitech G402 Hyperion Fury - edition ( i bought that in sale around 2k if i remember correctly), its not as heavy as mx518. It will take 24hours to adapt to any new mouse and the performance 402 provide is unparalleled.
i moved to this mice after using razer for 12+ years, and i feel i was throwing my money in drain by buying 4 razer in that period. Razer has flimsy build quality in comparison to Logitech.
