These are going to be perfect for my wedding, I’m so excited to use them! They’re super light weight, come individually wrapped, and the batteries are already in them! We’re going to use them on the dance floor and then for our exit!So of the guests had a great time with these on the dance floor at my daughter's wedding!I don't usually write a review but I have to come back to give this a 5 star rating. It is hands down, one of the best party favors for kids birthday parties and then some.I always HATED giving out party favors that end up to be a bunch of candy and junk in a bag that will all go to landfill with no purpose. This is a good size stick that can be handed out alone for each kid so I don't need to dress it up with additional junk. Then, it really works! I haven't checked individually but for the ones that the kids turn on, they all worked. It also lighted up very beautifully and tastefully. It doesn't feel tacky or cheap. I bought the 2 dozen version and at the time I bought it it was about $1.6 per party favor. You can not beat that! We had 13x 10 yo kids and I have a lot of leftovers. We took a few to a dinner party, handed it to the kids, and they had a BLAST playing with it at the restaurant. It also looked beautiful in photos! We still have a few left and I can give it out at any time, halloween and such. These foam sticks do not disappoint.One non-complaint cons is, that one evening dinner where I gave these to a few kids at our party, I could see the kids (10 years old) really attempted to break it after an hour of so bobbing at each other. So at the end of the night 2 of them were broken, but you can't complain!I tested them all to make sure they work. They work great and have great bright color. I cannot speak for durability or how long the battery lasts as my event hasn’t taken place yet.Party’s eventGot this for my cousin graduation party and it actually was cool and if you turn them on, there is a switch where you can turn it off and on.
