So I was sceptical about the overall quality of this but I'm amazed as is my son who has special needs and sensory lights are very soothing for him.
They have a huge spread and they are mega bright, we haven't used the music function but it connected with ease to my phone, was a bit tinny sounding but hey its only little.
Charges quickly and lasts for long time between recharges.
Really great and would recommend
