I love the colors and feel of these coasters. They match perfectly with my bamboo bar set. The price is great too. Very happy customer.

Good Review

Ex Input:
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 Output:
Bad review

Ex Input:
It doesn't really fit the Kindle HD and it's all bubbled up around one edge or another. I ordered it from Amazon for less than half the price offered by Best Buy.

Ex Output:
Bad review
