CareforYou Vacuum Twist Suction Cupping Device Massage Relax Biomagnetic Chinese Cupping Therapy Set (S+M+L+XL)

No written instructions on how / where to apply for best therapy

These were purchased for nipple enlargement. They work great. I purchased a second time because I like the 2 smaller sizes ( I don't really use the 2 larger sizes.) When you 1st start with them, don't go more than 15 or 20 minutes at a time as they are very powerful with a good suction. Use moisturizer on the skin before using these. It makes for a better suction and you can center the nipple as well. There is a bit of "grease' used to keep the rubber gaskets lubricated and flowing freely. It does not appear to be used as some people have stated. Both my purchases arrived within 3 days in sealed boxes and in individual sealed bags as well. I would definitely recommend this product again.

This set of twist suction cups are a unique design. I am somewhat new to the cupping technique. I found these so much easier to learn and perfect my technique than the others that have the gun which requires both hands, at times, to operate. These are simple and easy to understand. I was wanting to learn how to do suction and then slide the cup across the skin and these were very easy to do with that technique so I am happy with my purchase and will continue to use these with my paid clientele.

Function very well and hold suction, but will want to order 2 sets if you want to balance left and right sides:-)

Good suction

These things are entirely useless; they do not work as expected. They don't adhere to the skin. Period. Spend your money elsewhere is my recommendation.
