[Q]: This thing is a major piece of junk. It doesn't stick to the wall like it claims. You have to stand to play with it (cause all the cool stuff is at the top), and the extension pieces constantly fall off. I actually screwed it to the wall, but that lasted a whole 10 minutes as it wouldn't stay screwed into the wall. Then the scenery kept falling. Save your money and buy the cool batmobile or something.
[A]: Negative

[Q]: This DVD is one of my all time favorite musical DVDs. Miss Jackson proves why she is the highest paid singer in the industry. With a combination of costume changes, great choreography, Janet's greatest hits, and a sold out crowd at Madison Square Garden, the DVD makes for an excellent night of entertainment. I only regret that I was not able to see the concert in person here in my home town due to a cancelation of the concert;however, the DVD is definately a suitable substitute. I highly recommend this DVD to any fans of Janet, lovers of music, and owners of quality DVDs.
[A]: Positive

[Q]: Don't bother. It is next to impossible to get this product to work. Tried everything (USB, download driver, etc.) and nothing worked - with XP Pro. ended up in the trash.
