Query: Good content; poor software.

A good introduction to ASL, but a pain to get the CDs to work together. This should be on DVD -- or allow you to put all the content on your hard drive. Several times when I had CD3 in the drive, the software told me that I had to insert CD3. I could not find any tech support.On the positive side, the presentation of signs at optional speeds is great. Adding grammar is a real plus!
