It works ok, but could be more intuitive. There are too many steps to make it work and there is a timer for how long you have to hit the button...as well as having to start it by remote and having a countdown...really weird. For that, I didn't really like it and am returning it. As long as you don't mind having a countdown and a timer for each play, then it will probably suit your needs.Basically cliff notes on how to use it. They say watch the videos when I asked for help. You watch the 1 minute video and see if that would show you how to use it. Went to manufacturer's site and the product is not even listed for buying or support. Then I guess I have to pay the freight to have it shipped back to China as a return. The whole transaction blows......Fun to use. I couldn't make it work at first I had a 12 year old set it up.TrashI bought two of these and neither worked. Save your money, do not buy these! On top of that the customer service is terrible.I'm sure some of the uses you'll think of for this will be school-related, and those are great.Here's how we've used them:1. Homeschooling, with some of the same education ideas of groups ringing in except with individuals.2. Church youth group for timed activities.Do they work?Yes, we've had no trouble with using the four included buttons. The largest space we've spread out across is about half-a-gymnasium. No difficulties. The system works.This is exactly what I expected. It wasn’t hard to set up. Pretty simple and straightforward. It works great for our needs. We love playing games and making up games, adults and kids and with covid this has become a great addition to our home. You can make your kids do races and first to hit the button you can time their running lol it’s got many uses, not just a game timer, make up your own games. It’s nice to have especially when it’s loud and you want to make sure the person that knew the answer first gets credit, so you take out part where you rely on hearing which stops arguments, cause if your family is as cutthroat at games like mine, there will be arguments. Like I said, great addition, many uses, yeast to use.
