FALSE CLAIM… NOT WATERPORRF 
I used this product for water fitness. As soon as I jumped into the pool water got into the otter box and ruined my ipod. The company does NOT stand behind their product,VERY POOR customer service. Had an “Oh well” attitude about my Ipod being ruined by their product. WOULD RECOMMEND STAYING CLEAR OF THIS COMPANY!! Go with H20 Audio instead!
poor
I used this product for lap swimming. As soon as I jumped into the pool water got into the otter box and ruined my ipod.
Durable, Highly Recommended 
I have had my Otter Box for about 3 years. I have used it to shield my IPOD during my workouts, which occur 5-6 times per week. I have dropped my IPOD on the ground numerous times, and there was never even a scratch on it because of my Otter Box.
I must note that I have not used the Otter Box for swimming, so I cannot comment on its functionality for swimmers. I highly recommend as an IPOD Nano protector for workouts.
Great stuff and perfect service!
I have the otter box for over a year know and although I switch the ipod often between box and car, nothing happened yet! Only the audio jack got corroded after one year of intensive use (2-3 times/week) but I got a new one without any questions asked! Great service!
Great case, but heavy 
I love this case. It does what it says. I only have two minor complaints. The case doesn’t allow you to use the nike ipod with it so if you run, that’s a drawback. It’s also a little heavy. I rubbed a “hot spot” on my back with daily use with running.
