Query: Beware of Broken Buttons

This is a great player when it works. I love the features and sports timer. The earphones are uncomfortable but no big deal seeing how cheap replacements are. The problem is the buttons stop working. At first they seem a little difficult to push but then they just stop functioning. Two buttons went out after three weeks of use. They were the Volume down and Next Track. Returned to store for exchange and then the same thing happened again to the second unit only now its three buttons including the most important Menu button. Will need to send item in to Creative now and wait. I will not be surprised if the third one I recieve has the same problem. This issue has been brought up in the creative fourms and I have seen it reported other places on the net. If I had to do over I would not buy another one of these. Basically a little bad engineering ruined what otherwise would be a great product.
