My previous H20 Audio Amphibx case worked well for 16 months of swimming about three miles a week in my gym's pool. During my summer trip to Malaysia, I managed to break the latch, but the seal still worked. However, being a bit concerned with the possibility of the door flicking open underwater, I decided to purchase a new one. My previous one had been purchased at swimoutlet.com, but they were sold out of this model. So I found what is allegedly the identical model here on Amazon. The seal never seemed to work properly, and the unit "deflated" in water, but no water got in. Then, a few days ago the seal separated and flooded the interior, ruining my Zune 120. The old case sits here, still functioning despite a broken latch, and the replacement one has brought nothing but woe and anger. I have to buy a new mp3 player now, as well as a new waterproof case. It will not be this one.
