Although I am using it several times, there is a merit that there is not a cheap sponge.
First of all, it is hard to get back and it is good to hold, froth is cleaned and water is well well and the size is easy to use.
I do not know how many times I've repeated it. The net that wraps the sponge is moderately solid, and it also drops dirt well. It is easy to wash the inside of the cup without having to change the front and back depending on what to wash. The price is expensive, but I think that it is advantageous because it is strong and can be used for a long time. I am happy that two sets come out again!
