So far, the product is great! I use it for about 3 months and it is almost in constant use.
I fill the water an ever so that after freezing all possible ice cubes are individually and I this is also so out break (bend slightly, shake and bang on the table helps work wonders!). This works very well so far.
Also, I have no problem with the closures. Despite frequent opening and closing, I can not detect any cracks or similar defects closure. So far the can close properly.
However, I make sure not to put in the dishwasher such doses. I find that does the products not good.
Great thing and a full purchase recommendation!
