[EX 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.
[EX A]: negative

[EX Q]: I ordered this product but received the joint supplement instead. Amazon provided me a refund, but I still want to try the holy basil. If I order again, can I be assured I will receive the correct product?
[EX A]: negative

[EX Q]: I bought this to use in my salon. After about a month it stopped charging. Of course I had thrown the box away. The cord works, tried on a coworkers shaver... but mine won't charge anymore, and I had bought 2 additional heads to go to it
