TINANA Crystal Clear Ice Maker, Silicone Ice Ball Tray, 2" Large Ice Cube Mold, Sphere Ice Mold, Black

I've been trying on my own to create perfectly clear ice, however, it was only in bulk and I created a mess. This product creates the most perfect round, clear ice balls, ready for a classy cocktail that fit nicely into my old fashion glasses. Now the advice I'd give the manufacturer. 1. provide clear instructions for the first time user 2. being an ex-engineer I figured it out 3. new users, make note of (and or take pictures with your phone) as you unbox and disassemble the ice maker. 4.keeping the original orientation of the silicon inserts makes it a breeze when reassembling it. 5. once frozen, patience is your friend, and with small gentle movements on the out tangs will allow air in between the foam insulator box and the silicon inserts. Each tiny movement turns into bigger and bigger movements and wha-la, your frozen ice cube silicon form will be in your hands ready for separation. 6. the waste ice at the bottom of the foam insulator can be melted by running hot water over it or let stand at room temp until it comes out. -Have fun. -You'll be pleasantly surprised at the results 24-36 hours later.

Quite simply it does what it advertises. I would suggest that you use filtered water and let it freeze for at least 24 hours after that enjoy your beverage.
