Q: This rack arrived so twisted/bent that it can not be assembled. I wanted it for an upcoming trip but I will not have enough time to return it, wait for the new one to arrive before my trip. Absolutely useless junk with no QC. I will just return this item and go to a local business to get one. Thanks for wasting my time.

A: negative

Q: Sound quality is alright--for about 5 minutes; the headphones volume cuts in half within a few minutes of using, to the point your music is nearly inaudible in a room with ANY noise in it. This is from a FULL battery, mind you. I looked through reviews and didn't see this point, so I'm thinking I may have gotten a defective unit that can't deliver proper voltage from the battery during usage. In any case, I'm very disappointed with my purchase.

negative
