I've been using one off and on for about 4 years. They work in the sense that it helps people quantify/gamify meditation practice, which can work as positive reinforcement. I also find it much more relaxing than guided meditation. If you're unlikely to continue a meditation practice, you'll probably use it a handful of times and will end up in a drawer, and you pull it out occasionally as a novelty to show people. Still, would recommend.
