It's a nice desk, fashionable, well-made, holds plenty of weight without complaint. It schedules when I should stand up and sit down, and the "breathe" gentle reminder is effective without being obtrusive.
The biggest downside is that the sensor that detects whether or not you are standing next to it is extremely picky about distance. Apparently I often stand too close and so it doesn't always recognize that I'm there and credit me accordingly. Also, it would be better if it integrated with Apple's HealthKit in addition to their own cloud stuff. Do I really want data about when I'm at my home office desk to even exist, let alone be stored in the cloud? No - that's pretty much a "Let's figure out the best time to burglarize my house" toolkit.
