I see them selling tons of these. 10 year warranty is epic. Why only OC3D Approved Award?
If i had to choose i would go with HX over HXi. I would like to think the newer product is more optimized. Like restyling models of cars are usually much more reliable. And i don't need link that much.
Just been on Amazon and the HXi is £35 cheaper, I suppose you are paying more for a 10year warranty and newer components. There's 50p difference between the 750i and the 850i at the time of this post.
