Pro Easy-to-use app
The app isn't confusing at all. It gives you 9 dynamic lighting options to choose from, such as magic hour (simulates a sunset), northern glow (simulates the northern lights), and cozy flames (simulates fire). Each of these has an option to adjust the intensity, although instead of just adjusting the time it takes to move from one color to the next it also changes the colors. For example, the Cozy Flames turn green-ish instead of the regular red with yellow and orange bursts.
Con Very dim light
The 430 lumens brightness of the Elgato Alvea is almost as bright as a 40-watt bulb, but not quite. These lights will be very expensive to use as primary light sources, as you'll need many of them to sufficiently light up a room. They are really only cost-effective as accent lighting.
Con Limited coloring options
While most smart bulbs let you pick from a color picker, for solid colors the Elgato Alvea has 7 to choose from (blue, green, orange, purple, red, white, yellow). Each shade is then adjustable in both brightness and shade, however it would have been much easier to just use a color palette like most other smart bulbs.
Also, while the nine dynamic lighting options are easy, they are the only dynamic lighting you can achieve. You can't set up your own dynamic color palette.
