Not as bad as reviews say
As of purchase in June 2025, lights work fine and so does the app. One of my lights wouldn’t connect to Bluetooth, so I had to reset it like instructions say to. It connected fine after that. If app ends up failing, like many reviews indicate, the buttons on the lights work fine also. This is not a premium product, but it’s not a 1 star unusable product either. (That could change over time).
