Marvel Universe Live question

[Vinny0026]

Hey kids - I'm taking the kids tomorrow to see Marvel Universe Live

they have an option to buy this bracelet for 25.00
it says it is interactive with the show.

My guess is that certain parts of the show will send a signal to it, it will cause it to light up.
I do not think it has any sound.

I wanted to know if anyone has gone to the show and has seen what it does
and if it is worth 50 bucks (I will be taking 2 kids)

or should I have them buy something else at the show.

thanks for any info

Have not been yet... but ordered tickets months ago. From the reviews I read, it sounds like it isn't worth it.
