In storage container which is too small, moreover MUCH, melt the "ice" quite fast there.
After all, the melt water is running again directly in the underlying water tank.
Construction itself is not bad.
But it must be significantly more powerful, faster, much more than 9 "bit" at a time,
larger storage containers, like even larger water tank (although the 3.5-liter is not bad)
Whether it really comes out the vaunted total amount in one day, I would also doubt very much.
And - even the annoying thing with the protective film, which can be not completely replace hard or in the cracks, even annoying.
