Product review (5 stars): Gimme big cubes!
Tried the pair of big ice balls and loved them so we decided to go for this tray since it does 6 at a time.  Between the tray and our two ice balls we can have both daughters and their husbands over for dinner and have enough for everyone.  They seem to last way longer than I expected before they melt.  You just have to have glasses with a big enough opening to take advantage of the big cubes.  Love them.
