Another positive aspect is that you can disable the screen lock the phone, when the clock is connected to the phone. This is in addition to the display of incoming messages the biggest selling point. Precisely because of the finger scanner at grade 4 still is to roam about it. The GearFit saves the hassle with patterns, PINs or just the drüberstreichendem finger.
The battery life is approximately 4 days is not a problem. If you compare the activation gesture, so that the display is no longer concerned, if one tends the clock itself (you already know, if necessary by the illumination function in Casio watches), to get I like 4 days otherwise about 3 days duration.
The size of the "clock" is actually just right. It is very narrow, so disturbs but barely.
For these mentioned features about 100 are absolutely fine. The MSRP of 200 I consider, however, be exaggerated.
The actual functions of the clock are not bad either. "Functions" - let's say "function" because in itself would otherwise only the heart rate monitor. That you can use this as part of workouts, the expected frills this feature has been around. The heart rate monitor is amazingly accurate, at least the deviations were compared to my OMROM M500 in the expected tolerances. Tolerance means here: even if multiple measures with the M500 a row, you never get the absolutely identical value.
As part of training the heart rate measurement works very well, they hardly notice (happens also only visually).
The sleep measurement is quite nice, but boring if you always recognize the same pattern. For me, I usually accounts for about 80% of solid sleep.
Otherwise, the part can not, but it's also not a phone replacement, but an addition. I think it is splash-proof, which is not much, but in everyday life I see no Beeinträchtungen. Wash hands is no problem when you sweat during exercise, and nothing seems to penetrate into the housing.
Positive is that you can change the strap, if it times breaks. Yes, the bracelet itself is really cheap, especially the "locking mechanism". That even a Casio Clock for 10 more. On the other hand you get small loops that fix the problem for a few euros. In my view, but not a must. Only drawback, however, the bracelet the two closing thorns: these are obviously plated and solve at me from an allergy. Even that can be resolved quickly with the small loops.
