This reminds me of the County Fair booth with the red, yellow and green lights. When the light went green you had to beat your opponent to the gas or get a shock.
This one is probably best for older kids or adults.
Pros-People who purchased this said it was a blast and very fun at parties. SoOmething unique for under the tree.
Cons-purchasers complained it was very light weight and lacked clear instructions. The shock level is adjustable by a switch on the base. Music plays and when it stops you have to not be the last person to press your button. If you are last you get a minor shock. Not for use by kids without adequate supervision.
Also if you jump the gun and hit your switch prior to the song ending you also get a shock.
