How is the V. motion for left handed kids?

I've been trying to read through the journal posts by the moms who have tried it. I can't find anyone who has said that her child is left handed. My son is left handed. Before I buy it, I would like to know if it really is better for a left handed child than other things. I am specifically looking at getting it as a Christmas present because I want to find things that encourage him to use his dominant hand. I saw on the video that you can change it from being a right handed controller to a left handed controller. Does anyone who has tried it have a left handed child? My daughter is right handed. It would be really nice to know if they would both enjoy it equally based on their dominant hands.
