Sony Walkman D-E301 Personal CD Player

We bought my son this cd player for Christmas. First of all, let me start off by saying that we didn't spend $100 on it. We got in on sale at the Wiz for About $59.00, and it was well worth the money, My son absolutely loves the quality and sound of it. I recently started using this while using the treadmill. At first I was a little reluctant because I thought it would skip. But I decided to give it a try anyway. Boy, was I pleasantly surprised. It didn't skip at all. What a pleasure. Also I have found that it is great on the batteries. My son uses it all the time and he just now has changed the batteries on it. Roughly around 3 1/2 months.
