The product assembled easily and fairly quickly considering we did not try it out prior to the party we bought it for. We set it up to spray foam into a borrowed bounce house and after some adjustments managed to get most of it to spray into the bounce house and not on the ground. The kids were having a blast for about 2 minutes until they all got it in their eyes and We had to hose off faces and I tossed a dish towel in so that they could wipe their eyes. Then they started inhaling/swallowing some accidentally. One child coughed for the next 2 hours and went home complaining about a sore throat. My child threw up. Then we read the warnings on the bottle about not ingesting it and to was eyes for 10-15 mins if the solution gets in there. Luckily, the quick rinses we’d been doing were fine, but overall I’m not at all impressed with the solution. Would have expected it to be nontoxic like kids bubble solution. That said, the machine worked great and all but one kid stroll had a great time, so inThe future we will try out the suggestion in many of the reviews to use baby shampoo. I’m sure that will be easier on the eyes and taste buds!
