    Decent Speaker
    I bought this speaker to go with my projector and firestick when streaming TV and movies. It's a decent little speaker with sound that fills my small back room. I've had no problems connecting it with bluetooth although it starts to cut out if you stretch the distance to the top end of its range. I've used it for music all over the house, down the garden, in a tent and in the car and found it to be reliable and good quality. The lights work, but aren't really of any interest to me and the drum feature is, frankly, bizarre, but overall this has been great for its primary function - TV and Films on a home movie screen. The app is really good, too.

    Waterproof speaker Rocks the Bathroom!!
    My teenage daughter has turned our bathroom into her own personal disco. The extra base booms around the house!! Excellent sound quality from a small speaker and a nice mesh finish makes it look cool!!
