I have a Razer Abyssus now, so i will tell you about my impressions in comparison to Salmosa. It's quite easy to compare technical specs, so i will skip it
. Visually, difference is subtle, shape is profiled better, handling feels nicer. It has a blue glowing logo, which is nice but makes your dark room lighter. Movement is natural, the diffrence is evident. With Salmosa, i had a impression that i fight with the mouse sometimes, this felling is gone with Abyssus. My overall opinion is very positve, Abyssus does the job better.
There is a strange thing though. http://razerblueprints.net/index.php/component/option,com_smf/Itemid,99/topic,8628.0/
I have SS QCK. I can confirm strange verical lines, my circles are perfect though
. With rotated mousepad there is no such problem. People there (and even here in other thread
) suggest exactpad.
