I purchased this audio CD with great anticipation of practicing basic Spanish grammar as I drove to work. However, when I put the CD into my car's multi CD player, it skipped and jammed. When I finally ejected it I saw the problem. The CD has a paper label on it which causes CD's to jam in most multi-CD players. I then thought, "I bought it...so I'll just burn it to another CD so I can still use it." (btw, this does not violate any copyright law since it was for single, personal use) But the recordings are of such low quality, all I got was a buzzing noise out of the copies. I never got to hear the lessons so it would be unfair to give the product a one star rating. But since the publishers of this CD refuse to use good quality CD's, I gave it a generous two star rating.
