Anyone use a SwiMP3?

I got it for my birthday last year (March) and I havent had too much opportunity to use it, because I am on a college team and well we're not allowed to use that during practice, but what time I have used it I loved it! It's really great if your swimming by yourself or doing long swims (I did several 1-3hours swims back in the spring and loved it for this purpose). It's not as easy to use when your doing fast time interval sets, just because its distracting and I had a hard time keeping it on my head with a flip turn at race pace, but thats not to say its impossible!
