I bought it so I can keep all my pet supplies in one place and it seems to be holding up well. loved it just watched it a second time! I have never seen anything like it, works so much better than the Beats "tangled free" flat cord. I needed a couple of small spice racks to fit on my narrow cabinet door. Alright, this is as far as installation and first impression goes. I do not recommend these batteries. The size was off by at least 1/2 inch. If you dont care about the noise blocking, get the 373 PC instead - theyre better sounding and more comfortable. Great piece of exercise equipment to have. They are not shipped in their Nike boxes, they?re shipped in a regular brown box with a message on the inside saying ?the original box was damaged during transit.
