That said, their newer ones also seem a bit more slippery / harder / less precise than older ones, in my (subjective) impression.

People want to know two things: 1. Is it quick? 2. Is it easy.
Demonstrating the first is easy, but your product will live or die by whether you can demonstrate the 2nd, and its already working against you: First impression is an overwhelming matrix of letters. The video's demonstration ignores this, and explains "type the letters in the cell", and then the video moves on within a second, when he should slow down and explain.
My recommendations: Don't say cell, say box. Its less technical. Don't assume people realize that each box has a unique combination of letters, tell them. Say: "Each box has two letters, and no two boxes have the same two letters. Type those two letters and your cursor moves to the box."
I wish more keyboards would integrate that little red Lenovo mouse nub.
Some thoughts:
- allow me to maximize the youtube embed on your site, I can't really see the video clearly enough to gauge the product so had to open it on youtube
- little green cursor in your vid is very hard to see
- took me a long time to understand that your cells were rectangles, so "2 characters of any cell" didn't make sense for a while, maybe you could emphasize it (if only for the video)
