I've got a five figure stereo system. And I really like visual effects like Spectrum analyzers. They are tough to find and most of them are eqs. I am very picky with my stereo and pretty critical of crappy products out there. These things blow me away! They are probably my favorite thing I've ever ordered on Amazon and I'd be embarrassed to find out how much I've ordered over the years! They are well built, very good looking and a lot larger than I was expecting. Although I would have been happy even if they were smaller. I got the one with the app. My phone warned me it was potentially dangerous but I went ahead and downloaded it and I'm sure it's fine. It is incredible! It has probably 20 plus modes that are all very cool and different. So many colors to choose from and I love the fact that it's got a brightness control and a sensitivity. I bought four of them and I love the fact that the app controls all of them at once. They connect perfectly at first and every time. They are responsive and vibrant and have little stands that come with them or they come with little sticky pads. I'm pretty sure the battery only lasts 3 hours or so but I have mine permanently plugged in to a surge protector so they come on with my stereo and are just a perfect addition to the visual appeal. I have no complaints about them at all. I spent about $36 on four of them and I have zero buyer's remorse. If I can think of more uses for them I might even get more. Totally Blown Away how great these are. I'm very surprised about how many different modes and types of visuals it gives you. I doubt you'll be disappointed
