Pros
It's a cool product with lots of interesting challenges to solve. Making something that helps people live healthier, happier lives is certainly something to feel good about.
Cons
Office politics run rampant, and there has been a lot of turnover of high-caliber individuals who have been left frustrated by the old-guard's poor decision making and incompetence. Simply put, some of the leadership team are out of their league. They spend more time on trying to maintain their image/standing with the CEO instead of focusing on how to scale and improve the company/product (i.e. close-minded to new ideas, withholding information and shifting blame to other teams, downplaying team members' accomplishments and inflating their own, inability to make decisions, etc.). It was disheartening to see employee after employee join the company only to leave within a year after having enough. HR and the CEO are undoubtedly aware of these issues, but lack the backbone to actually do anything about it.
