I bought two sets of these. They're priced at $9.50. But, when they arrived, the price tag still stuck on the item says $2.99. Nice way to hide your "shippign cost" ($6.51) from your customers! This company goes on my "Never Again" list!

Ex Output:
Negative

Although the music of this CD was just what I needed to teach a lesson on early jazz and it's influence on the artist, Mondrian, I was disappointed that it did not have the cover sheet shown or any information about the artists. The CD package was broken.....Other than that, it was fun to play it as the children in my art class painted their own version of"Boogie Woogie Broadway" by Mondrian.Art Specialist --- Las Vegas, Nevada

Works fine on the PowerBook G4. Doesn't have an LED to tell you it's on and, of course, doesn't have a smart plug to show charging status.
