Amy, Don did a study on how lining up the knuckles effects bat speed. By not lining up the knuckles and being offset they found the impact was about a 5% improvement in bat speed. The study was done with Sue at ULCA, I believe. So the facts support this.
If you have a bat speed meter, you can do the same study. Put a sock or something on the hands that allows the bat to move during the swing in the hands and see the impact. I think they used plastic wrap.
So I'm not a supporter of this toy.
