just plugged in my new aby.
First impression about package :
no stickers inside, poor package at all.
about mice:
weight feels good, shape feels good. scroll wheel feels good. mouse feets very thin and its bad Imo.
old aby shape force you to use claw/finger grip. new shape more like kinzu if you have realy small hand you can use palm grip but its still good for claw/finger grip.
so i am not disappointed.
Just draw few flat lines in paint looks pretty good, no jitter.
The one that's most likely not to have the jitter problem. For me it was abyssus transformers edition, bought it 3 years ago, works perfect until this day
Could you test it on a QCK in paint? a bunch of very slow horizontal and vertical lines at 450 & 1800 dpi has shown jitter on every edition of the aby i've tried.
The new abyssus is much better. Old abyssus faults were: jitter, terrible tiny mouse feet that felt unstable and shoddy build quality. Also only 125/1000hz setting when 1000 was unstable. New abyssus 2014 fixes ALL of that, brilliant large and wide mouse feet for a much better stability, default 500hz for best tracking, no jitter, really solid build quality.
Hope this answers your question.
