Ah, OK. It's odd that they market it under two different names, though. I have to say, eye coach is kind of lame. They should stick with HAL. It's certainly a better name than "The Contraption."
Anyway, I'm kind of surprised that the Eye Coach video has this little girl whacking at the ball like that. I guess "Parents who like their kids to whack at things" is one target market, I suppose. I'd never buy something like that for my kid to practice with, as it reeks of something the kid would use for 2 minutes before getting bored, requiring me to keep it in the basement.
I did think it was terrific for working on stroke mechanics with a pro.
