For indoor use, the benefits of Fitty is limited in my eyes! The (via Setup) set stride length will probably rarely reliably adhered to walking around in the apartment, the caching of the 13 steps up to the activation of the display from the 14th step confuses me more than it convinced me, so down I let the thing more on the table ... But outside while hiking this little helper is really great! Yesterday, when first used more than 17 km I could see that the count of steps reliably worked, the parallel display of distance traveled and real walking time is a valuable piece of information about one's own pace, and the display of calories consumed is at least a nice gag, the can enjoy the Wheat beer after arriving without much remorse ... The split function is a good support for excursions where the hiking example purports: "... after 260 m bear right (not in the lane just before) ..." because you can precisely retrieve a spontaneous distance between here which is (just 3 sec. "Mode" key "=" then subsequently added to the total distance a ', then the counter starts at "zero", when the desired distance (in this case to 260 m) again for 3 seconds. " press Mode ", then the display jumps back to the totals back). I am otherwise not necessarily a friend of them to do everything electronically, but here I think the Fitty compared to my previous mechanical K & R pedometer (Twinstep) for a real improvement, and then at this price !! One point deduction merely because of the mounting option (only at the head end), here I would very meet, albeit at the foot would be a way to hang up, so you could fix this thing, for example, the belt and could read while running simply by clapping.
