While these are Christmas presents, I opened them to test them out before my kids got them. They were super fun to play with. I plan on getting them a couple more after the holidays.

These musical bands are just ok. They connect to my phone without hassle and there’s no lag unless you hook up the sound to a wireless speaker, like I did to my Bose, then there is a significant lag. My kids are 6 & 7 years of age and they found it interesting for maybe an hour or two then it’s another toy box item gathering dust. I would not have bought these if not for the deal of the day price. They may be good for those who really like to make noise when they move about. One thing though, you just have to have the phone with you so you can hear it. The sound comes out of the phone and not out of the bands.

We bought these for my sons 5th birthday and he enjoyed them so much he wanted to take then every where. However I would suggest buying 2 boxes or more, since it can only create two sounds and it would be more fun with multiple sounds. It would be more fun if it could be played through the tv instead of on someone's phone or iPad.

My 4v yr old and i have lots of fun with this. Awesome idea

It looked so nice on ads, and YouTube videos, but in real life sound get behind, variety is limited. Buy this only if you are really like to dance.
