These work surprisingly well. They make perfect snowballs in seconds.I got these for my kids and let me tell you, these are the best thing ever created!! This is the easiest way possible to make snowballs for a snowball fight. It takes seconds. It’s so much fun I even enjoy making snowballs with them. If you live in a snowy area this is a must! We ended up ordering the double ball one, and the heart ones too. So far they have held up really well. We’ve been using them for 2 months now and they haven’t broken yet. We are very happy with our purchase.Works well- I deducted a star because they did not send the colors in picture. I would’ve bought a different set but I liked the colors pictured so I as disappointed to receive generic red blue yellow and green. The product itself is greatWhy make one snowball when you can make 2?! These have been a great addition to the lockdown of 2020. The kids (and adults) have had hours of fun with these. Surprisingly, none of them have broken even though we keep them outside all the time. They are exposed to cold, heat, snow, wind, and water.One of them worked wonderfully, but the 2nd one didn't. The one that didn't work well couldn't hold the ball-form well. No matter how much or how little snow we used or how much we packed it, we couldn't form a fall and ended up with half-spheres that were tough to get out of the mold. But super happy with the one that did work!These work great! My kids love having snowball wars. They make a bunch and then go at it. Perfect snow toy!these work fine for making snowballs, but the screw holding the two pieces of plastic together is plastic (rather than metal). I would make sure to get ones that have a metal screw so you dont have to worry as much about them breaking. assuming that you dont care, and that they dont break though, these work perfectly fine and are good at making snowballsLove these! My little guys can make snowballs on their own. These have been a favorite outdoor toy over winter
