Only looks good in the picture, and the materials are very rough, stained and cheap. The copper is a lining not pure. I should've know due to low price but even at the price it is definitely very poor workmanship and not worthwhile. Now I have spend more money getting something better so as they say; better to spend wisely then hunt for bargains.

Ex Output:
negative

Ex Input:
Quality product that adds the small detail to a well detailed car. Buy a couple of pairs, unfortunately other people like them too and will replace them for you on your car! Good problem to have since it's well like but frustrating

Ex Output:
positive

Within a couple of weeks the center of the futon was sagging, and by the 2 month mark was completely flat in the middle, even with regular rotation. Could not sleep on it without rolling into the center. Worst futon mattress I've ever had, and no returns.

Ex Output:
negative
