A: positive

Q: 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.

A: negative
