Query: Good Sound - Poorly built

I purchased 2 of these believing that they would be great for working out (one was for my wife). They sound good and the software is easy to use.However - I would not buy this item again. The supplied sleeve to carry the player on your belt or in the supplied arm strap is not cut properly to access the buttons properly. The arm strap is not well designed to hold the player - the player will actually flip out with repeated arm movements(runners beware). Then, God forbid you drop the thing at all it will fall apart. It is not durable and the design creates situations where it will fall. I've had mine less than 6 months and have not used it very much. After it popped out of it's strap a couple of times, the unit began to separate at it's seem. There is no way for a consumer to attempt to put it back together properly. Too bad. I strongly advise against this item as a sports mp3 player - it is simply not durable at all.
