Query: Poor Design

The action jacket(glove) doesn't allow easy access to the controls of the Sansa MP3 4gig flash player. I had to cut out the plastic windows in order to move the control wheel. The glove fits too tight so it is not easy to remove it from the glove to set the sound volume, song choice, etc. It really doesn't seem that the unit was tested for ease of use. I have shelved the action jacket and am using the mp3 player without a jacket. Not a happy 'camper'.
