Party Speaker Happy

Love this speaker. Easy to use and controls are clear. I expecially enjoy that the speaker pair with a downloadable app that lets you control the speaker from your phone. It being waterproof is also a nice feature.

Best Thing I've Ever Bought!!!

I absolutely love my partybox, it's lasted 3 years, i use it almost every single day, i've taken it in the boat, to the beach, in a paddock, in a shed, in the rain and still perfectly working, the battery life is great, the sound is amazing, the lightshow is great and syncs with the beat of the music and it still a good brightness, that's bass is good and the app makes it even better, it's easy to take places and i absolutely love it.
