I have a 2012 DeathAdder, what do you think of the Sensei? The DeathAdder is probably the comfiest mouse i've used and fits my hand pretty nicely (small but I palm it), would you recommend having a look at the Sensei?
It's not
as comfy because it's an ambidextrous mouse so has to cater for two types of grips I guess.
Overall I think I prefer the Sensei. The side buttons, of which there are 4, are of a higher quality and it is a fraction lighter which I prefer. The feet on it are huge too which makes for a somewhat smoother feel across the mousemat. If you're in the market for something new deffo worth a go - I love it so far.
Sensei is probably a fraction smaller too.
