All 4 are very good, even if they consist only of plastic.
The white standard is 6x better clean than manual cleaning. I can only confirm. Cleaning the facial skin so that is great. Although it is shortly after slightly flushed but I feel much better and have little impurities or the like. And who makeup used can thus clean his skin pores.
The pink brush is very soft and therefore well suited for a gentle cleansing for sensitive skin. I can only confirm. I since 3 days use the brush now always in the evening and since my skin is no longer flushed after cleaning and feels soft and clean.
The white-blue scrub brush can be great use for skin exfoliation. I'm so 2 to 3 times a month and then wear a mask on. The brush has soft bristles outside longer and harder inside shorter and it works well. Especially when you still used to a exfoliating soap or mask.
And the last brush is a fine sponge, because you can use for applying and incorporating cream or makeup. Since I do not use makeup, but like cream (yes you should give the skin moisture after bathing / showering or in the winter) or masks use, I use it for. At first I was skeptical. But even that is working fine. The skin is then almost a bit like after a massage nice relaxing and feels very good.
It should, incidentally, according imprint after 3 months change the brushes on the box and buy new ones. I find that bit confusing. Actually, it's all rather then how often they are used. I would recommend you not to renew after 3 months if they are used, for example, daily. But surely this is just an indication.
They are then but what concerns the price not cheap if you actually every two or three months have to buy a new pack again. I would recommend rather the brush in buying single offer after (the brushes there are also depending on the variety in the two-pack). Or maybe to look what other manufacturers offer as so - plus the replacement of essays.
Conclusion: I've found the cleaning brush last year super-well, as I had in my first epilator with it and use it regularly since. And since I naturally looked forward that there is now even more good essays to go with the well on the older model. Only the somewhat high price unfortunately somewhat tarnishes the joy. But the quality is really good and who wants to be beautiful ....
