The difference between Razer DA Essential and regular DA?

[Fantucis]

So i just wanted to know, what's the difference between Razer DA 2013 Essential and the regular DA 2013? I tried to check online, didn't find anything good. I know it's a lite version of the DA, but are there noticable differences between both of them? I was thinking of buying the Deathadder 2013 essential, because my Rival 100 is kind of dying.

one has green backlighting the other has blue? i use a deathadder myself (older 3.5g) and looked at the specs pages myself and dont see much different.

of course they could use different switches or sensors but nothing in the specs page to point that out.
