It is effective only for areas where hair growth is already somewhat weakened.
Use only on the calf.
Friends who recommended it to me also used it on their arms

Really useless. Only if you have many long hairs it will do the job. When they are shorter, it does nothing.

I had used something similar in the past, so I searched for it. The pros are the speed, smoothness, and lack of irritation. The cons are that it doesn't remove medium-hardness, thin, or blonde hairs on the hands (which I tried), it requires a lot of persistence, and some hairs will still persist. Maybe it works much better for wilder hair growth (?). I reserve judgment on the duration because I just tried it today, and on the ease of changing the attachments. Overall, I would buy it again with the understanding that it's not something that harms the skin if done with caution and care.

Perfect result, leaves the skin smooth. Very fast solution, without pain and irritation. The hairs grow a little slower than with shaving. They do not "turn" towards the inner skin. Also, its exfoliation is pleasant.

It takes a long time to sand each spot. It didn't even touch half of the hairs and afterwards my legs were rough and dehydrated.

It is effective for fluffy and soft hair like hands, belly, and legs if it has not been used with a razor.

For painless, it is very good!!
A little time-consuming but it does its job very well!!
For women whose skin gets irritated with waxing and then there are redness, it has the same result without the redness, just in less time!!!
Oh, and the hair doesn't grow back or get wild!!!
A+++++

While in the past I have used a similar product, this particular one does not work at all!!! It has absolutely no result!! I would not recommend it under any circumstances!

Quite a good product, it doesn't remove the hairs from the root, it somehow burns them, so it requires caution during application because if you leave it on for too long, it burns your skin. However, it does its job quite quickly but the result doesn't last long. It is convenient though for those who don't want waxing or want to avoid the pain of hair removal.
