[Amazfit] Miha1234:
I'm sorry rant ahead. But I've had enough.

I bought the Stratos, because I didn't really like my Mi Band 3 (constant connection problems and almost invisible screen in daylight). I wanted to buy the Bip, but I said, what the hell. Let's go big. Stratos also looks good (Bip does not). The transreflective always on display is also great. But here the good things end.

1. The watch is slooow. Sometimes it doesn't register a touch, and sometimes it registers a ghost touch. The menus are bad, the layout is bad, the navigation is bad (and slow). The watch is also way too thick.

2. The Amazfit app is abysmal. Once the acitivity is recorded, it cannot be edited in any way. Did you press "walking" when you started running by mistake (It can easily happen - see above)? Too bad. You cannot correct it. Amazfit can draw pretty GPS pictures and graphs, but that's about it. And it's so buggy, it's more or less unusable (see below). There is no internet page, like literally every other app has (Strava, Endomondo, Runkeeper), where you could edit the data. There is no homepage. There are no official help forums.

So, even if the watch and app were completely bug free, the whole package would still be, in best case, average. But they are not bug free. And that is an understatement of the century. I've seen buggy apps and gadgets before, but this one takes the cake.

3. When I got the watch, the battery life was a real rollercoaster. The watch could go form 100% to 0 in a few hours or in 5 days. Sometimes reboot or factory reset helped. And that is true for the watch as a whole. Three to four factory resets in a months is (was - it doesn't work anymore -see below) almost necessary for Stratos to work "normally".

4. Caller name on the watch started working with Amazfit app 3. It never worked before. So, this basic (and advertised) functionality started working almost a year after the watch was released.

5. So, you start to run/bicycle/whatever. You choose the appropriate workout, you wait for the GPS, you start, and.... nothing. You are riding a bicycle and the watch says your speed iz zero.

6. You are running, and suddenly you pace starts to drop like a stone. So, I run little below 5.00 min/km. Yesterday I was running, and suddenly I was at 11.00 min/km. Not in reality, just on the Stratos. I always run 6 km, but Stratos measured 4 km. A day before 5 km. I actually ran 6 km, as I know the way. Thank god for Strava, because when I got home and the Strava synced, the running length(and pace) was correct. But only in Strava. Amazfit app and the watch itself got the data wrong. No, I don't know, how that is possible.

7. So, I was bicycling downhill. Suddenly, my hearbeat goes to 160. 170. 180. Am I dying? I feel the chest. Everything is normal. The watch is just acting up again. A few days after that, I was bicycling uphill, usually my heartrate is somewhere around 130-140. Suddenly, for no apparent reason, my heartrate drops. 60. 50. 40. And I am paddling uphill in 35 degrees C! Am I Lance Armstrong? No, It's just the watch.

8. A few days ago heartrate and steps stopped syncing with the app. The watch is at 6000 steps and Continuous HR is on (and seems to work on the watch), but the app is at 0 steps and "no heart rate data. Syncing doesn't help. Rebooting the watch doesn't help. Factory reset doesn't help. Restarting the phone, reinstalling the watch, creating a new account doesn't help.

Let's end this. I paid 160 EUR for this POS. After many months on the market, even the basic functionality of the watch does not work. What does work now, might not work tomorrow, and what works, works badly.

Why are things like this? It's the age old truth: when you buy the product, you don't just buy plastic, steel and glass, you buy a service. You buy programmers, that will get your product running long after you bought it. And that's why Amazfit products just seem cheap. Because you just bought the plastic. Nothing else.
