The molds are as easy to fill as any others I’ve used. However once frozen, there is a bit of a learning curve to remove. I use a butter knife to loosen the sides, then squeeze from the very bottom while wiggling it back and forth. Don’t get crazy wiggling or the handle will just pop out of the popsicles.So not much of a learning curve but now I’ve saved you a wonky popsicle.Also, product is kind of floppy, so i use a shoebox lid to get it to the freezer.I like this product. It works well.These worked great. I used them once and made gross popsicles and decided I was never going to try again so I gave the excellent mold to my sister in law who I am sure will also never use it but it was a great product. Did everything perfectly that you would want and expect a popsicle mold to do.Great to make ice cream at homeI absoulty love this item. The sticks are sturdy and holds the Popsicles...little diffcult to remove them from the mold but with a little wiggling and some soft massaging, they come out nicely.I have been putting normal koolaid in these to make popsicles all summer and they have worked wonderful.Love my Popsicle mold.I used Slimfast and it takes an act of God to remove the popsicles! I have to run them under hot water to remove ?
