Review on Samuelworld Large Sphere Ice Mold With Lid, 4 X 2.5 Inch Ice Balls - Food Grade, Easy To Fill Round Silicone Ice Tray, Perfect Spheres Craft Ice Maker For Whiskey, Cocktails, Christmas - Gray by Kevin Samuels

I've made a few batches of these ice spheres. So far, I think the tray is pretty easy to use, and the ice spheres certainly last a LOT longer than the regular cubes my Samsung refrigerator ice maker puts out.The tray snaps together, and has a few interlocking nubs that snap together to hold it securely. I find the tiny funnels atop each globe make filling the tray a cinch. There is some spill over from filling the funnels, but I've not experienced any leakage between the upper and lower sections. There is a small hole at the top of each globe to let displaced air out as water fills the space.The material makes it very easy to remove the finished ice sphere from the tray, as they don't seem to stick much at all. Some gentle coaxing and flexing, and they pop out easily and intact.The globes are not crystal clear. They are mostly a cloudy white, which I think is a function of most home freezers, which allow trapped air and dissolved minerals in tap water to cloud the ice as it freezes. I've read that putting the tray into an insulated box so that the water freezes in one direction (from the top to bottom) will result in more clarity in the finished product.I tried using some Styrofoam around the lower 2/3 of the tray, but honestly, I didn't see any discernible difference.
