This suction cup is of good quality, taking easy and seems effective hand because I've used the one week already that my skin is smoother and softer. Now we have to see the long-term outcome of cellulite .... I would complete this comment in one month. It should be on use with oil (vegetable for me) or cream and adjust the pressure (not too hard, or risk of blue). In short easy to use. The small pouch is practical to keep clean sucker once cleaned. No instruction on the movements to do but can be easily found via the Internet so ... Despite a price a little high for my taste I would recommend anyway. PS: For those who are wondering if they should buy 2 I think it is useless because it does not seem practical to me to use two simultaneously.
