This machine works surprisingly well. My son loves when we set it up. It creates a large pile of bubbles very quickly. The only downside to me is that the bubbles are expensive to purchase, so you have to watch for them to come on a deal. I would recommend this if you are considering it.Worked great and beyond expectations. I order two just make sure I had enough foam covering the area I needed. One would had been enough but I do recommend two if you want spread foam over wide area. The foam lasted for about 30mins with 10 gallon packs.We used this first in May in the yard during a large pool party, then again today. Works great. It's top heavy for sure. So us parents can relax, we learned to use a zip tie up high to attach to a vine on the fence and use it on days where there is no wind, especially no wind changing directions. We run the power along the other side of the fence and place the switch in top of the fence. Kids 4-13 and some parents as well. We'd buy again.Bought this for my one year old’s birthday party and it was a HUGE SUCCESS. All the kids loved it and it was tons of fun for hours.Made the whole party all the kids loved it !! Half a package lasted us the whole party the kids loved hiding in the foam from the others . They planned all day in it it topped the water slide and bounce house !Edited: Now having used it a few times, the machine has already been losing its luster. The stream of foam is getting worse and worse, so it's not the best quality. It's fun but maybe keep an eye on when it's on sale, because the price tag is a little high for adequate qualityI bought two of these for a big kid event, and we had plenty of foam for hours and hours of fun. But it is easily tippable, and if you are on concrete, your machine will break when it eventually falls over. Kids get a little rowdy, and the foam makes it hard to see, and just one little bump will result in $150 down the drain. We will strap our 2nd one on top of a structure to avoid kids running into it and breaking the last one. Kids thought it was great, and I see more dollars signs wasted, lolWe bought two of these and used a leaf blower. Best party ever!Love it.. It's worth every penny. The family has enjoyed it multiple times in our pool.
