So easy to carry around since it came with a hook that goes on my keychain. Its Free-standing racks for bottles fit any space and Stack each tier individually or detach side by side for versatility. I really liked these for studying. Finally, after doing extensive audio quality testing, we concluded that these $145 headphones sound NO BETTER than our cheaper, $45 headphones, which are also built to be much more durable and comfortable than this overpriced garbage. I am a size 8 1/2 but half sizes are not available. Also, the sound quality is perfectly fine for phone calls, which is how Im going to use these from now on. Outside of that it is a very great product. The delivery stated as about two weeks ( which it was) they came direct from Germany. These slippers are comfortable, a wonderful visual pick me up! I still Stand by my 3 star review.
