Nice in theory but not in practice!
I bought it for my little one's swimming pool along with its carrying case.
From the third use, the soap started melting and became gooey, the cord that it has to hold it broke because it melted and the soap got cut at the bottom, it sticks to the case and a large amount remains there when you try to use it again.
If there is any trick, I would like to know it, as it has already become useless!
