Overall, very good product
Overall, I have enjoyed the Eight sleep system. I am using my WHOOP to track my before use and during use data (approximately 5 months of pre-eight sleep pod data). I have noticed significant improvments in sleep quality (restorative sleep times), sleep stress, wake events, HRV, RHR, recovery score and overall mental clarity/energy/focus/sharpness throughout the day. To add background, I am an ER physician who has an erratic schedule which wreaks havoc on my circadian rhythm. I typically struggle with waking up after roughly 6 hours of sleep and not being able to fall back asleep. The eight sleep pod has helped with this as well. My significant other has also seen improvements in these areas. I do notice that the restorative sleep data between my WHOOP and the eight sleep pod are fairly different. However, the other metrics such as HRV, RHR, RR, seem to match up well. One thing I don't like (this is not specific to eight sleep because I have the same issue with WHOOP) is the sleep consistency score which both products constantly try and suggest ways to fix. However, the reality for me personally is this is a byproduct of my job and short of quitting my job, won't be fixed. I get tired of seeing that my sleep consistency sucks when there isn't a real solution. Overall, I really like the eight sleep pod and feel like it was 100% worth the investment. I am somewhat concerned about the longevity of the product but time will tell how that will play out.
