Hi Samir - they are brand new...if you see my pictures of the boxes. I only used them for about 2 months....which I can see your point...I'll knock off $25 for depreciation
Seems everything I read, there's only one version of the ACS (which is what I'm selling). I see AC has V1 and V2.
Edit - I found it. it's version 2.0.
Thank you
