P.R.
I used Hooked on Phonics with my daughter when she was 4 years old (she's 11 now). I thought it was a wonderful product. It was easy and fun to use, and my daughter got such a thrill out of learning how to read (I was so proud too). She could read by the time she went to kindergarten and is now in the highest reading group in her 6th grade class. It's a bit expensive, but it's worth the investment.
