Customers are satisfied with the Flex 2 Activity Tracker's ease of use, sleep tracking, water resistance, and compact size. Many appreciate its accurate step tracking and lightweight design, while some found the battery life to be insufficient. A lack of a heart rate monitor and display were also noted as shortcomings by some users.

    I have an iPhone and an Apple Watch. I was hoping to buy this and have it perfectly sync through the health app and the activity app but it only synchronizes in its own app. No way of having both communicate to share data. Maybe it’s for first time buyers of health equipment but not for me
