I bought so that I can enjoy steam and massage on eyes at home. This device can stimulate blood cycle around eyes and I do enjoy it. the only thing is, although in introduction it is said the steam volume is 10% more than the old model, I still cannot really feel the steam onto my eyes.don't feel much massage pressure, I wish it gave stronger pressure on both eye balls and side muscle. but I like the heat part.You can not really feel the steamLike: it is very comfortable. the steam amount is good, not too wet. Easy to use.Hard to say if it works on black circle or wrinkle cuz i only used it once.Dislike: the belt is very loose. the machine itself is a little heavy.It is good to relax my eyeBoth my boyfriend and me enjoy it. After all day long watching screen, the heat and massage help release the stress. It improved my sleep quality a lot.It is a nice device to have if you have dry eyes like me. The message and the steam make your eyes feel better.The massage power and the steam are too weak. You barely feel nothing after using that. It not worth to spend that money on this product.
