For athletes and hikers only.
If you only want to record steps in walks, sport etc. this is great. The ECG works very well too, and sleep recognition is good. The drawbacks are irritating and limiting: you need to take150 steps before it triggers. Who jumps out of bed and takes 150 steps? The accelerometer will register walking uphill, but ignores stairs, even at stations like London Bridge where you walk up the equivalent of several staircases in one slope. Other faults include a too short wristband _ on the standard size Fitbit I have 2 or 3 spare holes. The app does not operate in metres,maddening, yet hours slept are expressed in decimals e.g. you slept 7.72 hours . Maddening! Wish I had done more research before purchase, this does not suit me as around the house and garden accounts for much of my activity
