These are super expensive on the surface, but the time value is exceptional! Yes, it's truly possible to fill hundreds of water balloons in minutes. It would take hours to do that the traditional way, one balloon at a time and needing to tie each one. Yes, they're still pricey, but we don't do water balloons a ton so it's worth it for the time and effort saved. These also sometimes go on sale and clearance, so that's the best time to stock up. I'd typically pass on stuff like this, but they do work, they are fun, and again, the time savings alone is hard to beat. Kids and parents approved for sure!Used these for our end of camp celebration. The kids and adults loved it. It was a great way to end our camp. We are going to use this every summerIf you hate tying the end of every balloon in a knot, then this is your problem solver. It takes maybe 30-60 seconds to blow up about 50 balloons all at once AND tie them off. AMAZING! Completely takes away the annoyance of filling up balloons and tying them up for an hour and then it only taking the kids about 60 seconds to bust them all.?? Great productMy son referred this for the grandkids. Had great time for 3 generations tossing water balloons on a hot sunny day. Only problems is, 350 Al water balloons don’t last long, should get 2 batches.Filling them in less than 1 minute for 50, included seals when fullWorks exactly as the video shows. Filled up two coolers in a matter of seconds.Works well and is so much fasterMy kids go nuts for water balloons. They’re gone in an instant but at least they also were filled in an instant without labor on my part!My grandson had a blast with this product - lots of fun and laughter. I will surely purchase this item again and again. Thank you.My seven year old grandson loves them. Easy to use and loads of fun for the school holidays. Prompt delivery and packed well. Will certainly buy again.Purchased as a gift and he absolutely loved them. Even the adults were impressed at the design, would highly recommend for kids and big kids alikeBrought this for a family BBQ so the kids has something to play with to cool them down from the hot weather. Excellent value for money, but unfortunately the odd water balloons burst straight away after being filled with water. The children had a lot of fun playing with them so would recommend for the kids on a hot sunny day in the garden.All good as described and came well packed ****Excelente actividad, muy divertida, activa y entretenida
