After waiting several weeks to receive this, this does NOT work. At all...It's just more of yet another. Very disappointed. Wish we'd read up on other reviews before ordering.

Ex Output:
Bad review

These are by far the best quality and most durable dog toy I've found. I don't feel like they should be $25, but that's just me.

Ex Output:
Good Review

I had high hopes for this DVD and bought it after reading all of the good reviews. To my surprise, what arrived was actually quite boring. When the students sang these songs in concert - they were fantastic. After watching the performances on the DVD, you would think that the performers lacked chemistry or just weren't able to sing live. In a lot of cases (especially one song ) - there seemed no life left in their efforts. As far as singing skills go... yeah. Maybe it's me.

Ex Output:

Bad review
