Bests & Worsts Reviews from Amazon

Inside the box there is a VCD (chinese language only), and instruction book (both Chinese and English). I understand Chinese so I watched the VCD. Even if you do not understand Chinese, watch the initial part - someone did a demo how to put the cup on the skin and use the gun to pump, and how to remove the pump, then how to release air. The rest of the VCD talked about how to take care of your health in each of the 4 seasons (Spring, Summer, Fall, WInter) such as what to eat, how to dress, etc. I did not read the instruction book, but did my own internet research on where to put the cups to treat different problems. I heard from a friend who grow up with cupping therapy suggest put the cups (the big ones) on the back is the safest place, and put them on the place where there are "meat", not bones. I did this for my son (9 year old) who has asthma to clear up debris on the back by putting 6 cups (3 each side) near chest area. The suction guns are powerful, and just two pumps I see the skin raised almost to the silver point inside the cup. Two pumps are usually enough to get results. I used this for my son who got sick often and even after getting well he would continue to have dry cough that usually drag for weeks. I used the cups 10 min each time before bed time on the back when he was at the dry cough stage. I did my own research what meridian points on the back I should place the cups. The first time I did this I saw good results. He started to cough out phlem instead of dry cough, and after one week he totally stopped coughing and there was no more restriction in breathing. You may see the skin turned red or purple (like a pepperoni) and I read that was normal. That color change was due to "debris" and the cups cleaned them out. From my experience, the peppeoni went away in a few days. I used the cups for 7 days and my son's cough was less and less. After 10 days I no longer need the cups. I am sure I will use it again next time he get sick. The cups does not suck well on elbow joints, knee joints, legs, or ankles. And I do not find much use of the small size cups yet. I read that they are for face, or for babies, and I have been using the big and medium size cups. So far I only use them on the back and only need 5-6 cups, and got good results, and I am happy with them. Also after applying the cup, don't move, or they will fall out. My experience is that you definite need a second person to hold the cup and angle the gun right on top of the cup to suck. After you remove the cup, the skin may feel itchy so have some cream, lotion, or massage oil ready to rub a little bit to make you feel more comfortable. I dropped the cups a few times on hardwood floor from about 2-3 feet high and luckily they did not break. But it is hard plastic so there is a chance it will break if you drop it on very hard surfaces.
