[EX Q]: I bought a pair of these at first and one has stopped working just after the return day. They sound great while they work but if you want headphones that will last you buy something else. Also tried to get in touch with customer service twice for this issue, only got an answering machine most times. Not worth trying since they were never able to send me another headset to make it right. I'm done returning them. Amazon took care of them quickly so I give them five stars.
[EX A]: Bad review

[EX Q]: The light is really bright but its not very durable. It does work pretty well considering I have a few things on in my kitchen because it's kind of dark here during the day.
[EX A]: Good Review

[EX Q]: This is a great little machine that does what it says on the box. Don't think twice about buying one!
[EX A]:
Good Review
