I purchased the ring X so I could track my sleeping, fitness and heart rate etc. I do own a fitbit watch as well but wanted to have an option to be wearing other watches with the ring. The ring is comfortable to wear to sleep and I have used it in the gym lifting weights. However, it has already been scratched after a couple of weeks against the dumbbells although it was supposed to be non-scratch. I compared the ’step count’ with my fitbit and they are pretty similar. I would prefer if there is an option to choose the physical activity (for example,spinning, weights, workout, threadmill etc) on the app, like the fitbit and for the app to share the data with other apps, for example my fitbit. Upon receiving it, although the ring indicated a green light whilst on the charger, it was actually not charged and hence I had difficulty connecting it to the app. The online chat was quite prompt in responding to my questions and assisting me with it. After the first charge of about four hours, it finally was fully charged and could connect to the app. The battery life is not bad, at around 3-4 days before having to charge again. I do hope the app will have some upgrades to have some connectivity across some popular fitness monitoring apps so I can use it alongside with them.
