[EX Q]: I used them one time and pulled them out of my phone and wire went everywhere and now they do not work. Biggest waste of money and would cost me more to send back.
[EX A]: negative

[EX Q]: I was very excited to get this chair and it delivered on time. But when I opened package and unwrapping the chair I saw the few spot has damaged as a picture. That wasn't big but feels disappointed. The package is huge and heavy to bring the ups store to return so, I gave up to return. Design is good and comfortable but I can't say 100% satisfaction with this chair. No matter what defect is defect.
[EX A]:
negative
