Waste of time and money? No. If you want an ice cube tray that produces ammmunition shaped ice cubes, buy this. But remember, it's a novelty item, don't buy it if you 'need' ammunition shaped ice cubes that won't let you down... Soem of these reviews are far too critical considering the novelty aspect of this item.
Very poor cheap design doesn't make perfect bullets like the ones you see in the picture.
Not only do you get bullets with large gaps missing, they get connected by ice forming in the gaps between each one. Very poor, dont do it!
