I've had this mp3 player for a couple of months now, and I've been more than pleased.  When I swim laps I've always gone into my own world.  Now the world I go into can be customized by the music I've selected to hear.  Technically: this is a water-tight rig, it works very well for me, especially with the longer plugs that come with it.  The sound is clear - not outstanding, but these are earbuds after all - quite satisfactory.  I have even used it while driving home from the pool.  A couple of suggestions: use zip-tie loops to hold the ear bud cords to your goggle strap - if you happen to catch one of them with a hand in motion, you can ruin a pair of ear buds (as I did).  Get into a routine of recharging (USB connection to computer or USB hub) about once a week.  I like this little rig so much that I bought one for my 22-year-old son.

I have just had this a short while, but I am very happy with it. I did not find it difficult to load music on at all. The manual is just bare bones, but gives enough pertinent info. I also bought the waterproof Ipod case system; it works well , but is MUCH bulkier. I am very happy with this product. I have had some issues with water getting in around the earplugs, but I just need to find the right fit.
I wish I had bought this 6 months ago when I started looking at all these products!!

I use this product while swimming laps. It is a great way to help pass the time. It has great sound and holds lots of music. I swim 5 days a week for 1.5 hours each day. I only have to charge it once a week. It is easy to download music and to charge.
You do have to be really careful to make sure the earplugs are screwed in tight to avoid water damage though.

I use this MP3 while swimming laps. I loaded a book into it and love being able to lose myself in the story while putting in my 1/2 mile in the mornings. My only complaint is that, when I stop it, it resumes at the beginning of a chapter, not where I left off. That means that I may memorize an entire chapter before hearing the end.

When I purchased the first Waterproof MP3, I only used it twice in the water and then it stopped working for some unknown reason, which they sent me another one and it seems to be working pretty good.  And just in case you have to send the MP3 back for some reason, don't forget to keep the original package it came in, as this will make the process easier when sending back if you need to.

This product is exelent for training purpose, I have been swimming for about 12 years now, and choosed to buy one of these the swimming houers goes so much easier now.

Only problem I got with this MP3 was the earphones. I can't use the blue large ones since it hurts to much in the ear, so I choosed to buy one of the normal silicone atachements (just like those seetrough in the bag just bigger) And now it fits perfectly, no water gets in to the ear at all, and the music is perfect!!
