I received these tablets on a white bag with silver packs inside. No instructions whatsoever. They do not work. I am going to call my cc company (Visa) to see if I can get the charges reversed but sending back is not an option since it is so expensive to return to China.
If I had known these came from China I never would have bought them. I had a bad transaction before and to send it back would have been more expensive then what I paid. I can't believe FB would allow this. I am also going to make a complaint with them.
