This is an inexpensive way to add some fun to the room. It’s very easy to use and with the included adapters, you have a few options to use this. I was really surprised by the amount of lights this put off being as it’s so small. I was worried at first glance – but these are great and adds more light than you would think. It worked fine on my Samsung Note 8 – I just had to take my case off. If not using it with music, it still cycles through the colors – just not to the beat. The sound activation works, so if you’re in a room of people in party mode just the voices will make these lights dance. I’m impressed and really like these lights. They will make great stocking stuffers for the holiday.
