Query: Very helpful aid in learning the language

These really are great, I recieved the level 1 set about 3 weeks ago and I'm ordering the level 2 set today. I have the CDs and they have increased my ability with the language tremendously. I would recommend getting a book or separate program for the computer to help as learning strictly from these would leave out quite a bit, the verbs and tenses are probably easier to pick up through a book, but I found them very, very helpful. I did have the slight volume problem like others have mentioned but it was only minor and I found that adjusting the speaker control in my car fixed the problem. I was even able to fade the English out completely and focus on understanding the Spanish without the English help. Very good tapes(or CDs).
