Bests & Worsts Reviews from Amazon

In general, I like this tracker, but there are a few things about it that are super frustrating. I work as a nanny, and therefore spend a lot of time pushing carts and strollers as well as carrying children. I've found that this tracker does not accurately track steps when doing those activities, even when I also use gps tracking through the app on my phone (which also burns through battery and data). It's really frustrating to go on a four or five mile walk and only have 5,000 steps tracked when I actually took about twice as many. I had the Fitbit One before this, but I switched because I didn't have a great place to clip it other than my bra most days and it was very uncomfortable when carrying children. I also wanted to have a tracker that would monitor my heart rate and better track my overall fitness. As I spend a lot of time hiking on the weekends, I was very disappointed to learn that this tracker (unlike the One) does not track elevation gain. Considering the price tag for this item, I feel like those are two things that need to be resolved. I'm definitely a bit disappointed. Update: (photo added) Confirmed that it is about a 40% loss in steps and distance when pushing a stroller/cart. I lowered my rating because of my experience with Fitbit customer service. I contacted them because I think a 40%+ loss of data is an unreasonable margin of error and they basically told me that that's how their tracker works and if I don't like it, then I should look into other fitness trackers... It seems fairly obvious that they, as a company, don't care about customer feedback or retention.
