Fitbit Activity & Fitness Trackers FB417BKBK Editorial Review
The Fitbit Charge 4 has garnered a mixed reception from customers, primarily reflecting on its functionality and features while expressing frustrations about its band design and the transition to Google’s management. Many users appreciate the Charge 4's advanced health and fitness tracking capabilities, including SpO2 and sleep stage monitoring, which are valued for their accuracy under steady conditions. The device is praised for its precise step counting and Consistency with other measurement devices, such as pulse oximeters. However, customers have shared concerns about the rigidity and comfort of the default band, which some have mitigated by purchasing alternative bands. The reliability of the device's pulse tracking, particularly during changes in activity levels, has been noted as fluctuating, with instances of over-reporting heart rates during intense exertion. Additionally, the accuracy of calories burned has been questioned, with users finding this number can be inflated. The shift to Google’s handling of the Fitbit app has led to significant dissatisfaction, particularly regarding login issues and the transition process. Customers have expressed frustration with the lack of support and clarity from Google, urging caution about account migration. Despite the drawbacks, customers continue to appreciate the fitness features and overall functionality of the Charge 4, notwithstanding issues with the band and Google's customer service. ### Pros and Cons **
