So-so if you think about the money for value. First of all, it is single-use, so 10+ euros for one use is a lot. Secondly, in relation to the egg, even if you want to use it multiple times, the design is not convenient for cleaning. Because the sleeve is closed, it does not come out and behind the sleeve there are sponges that collect water during washing and do not dry at all. The only reason I give it 4 stars is that one use is good because the sponges are filled with lubricant and, combined with the sleeve, provide a nice sensation. But it should be considered for 1-3 times max, and those in a short period of time.
