Satisfaction so far, nice toy for big boys and good helper on the go.
Very good bike computer and navigation and many features that he is only gradually getting to know. Combined with the Sigma Ride and Komoot apps on your mobile phone, there's also a wide range of cycling routes. No problems so far.
I can't find a way to set personal data in Crash Allert. I can't even find a place to get advice..: -(

The second time I shop at Alza I paid extra for the 60 day return option, just in case. And the second time was completely unnecessary: -D I'm really excited. In size and controls it's still a "simple" cyclocomputer, but it can navigate you and collect stats just fine. Plus, it has great battery life, I estimate about 20 hours. I'm a bit annoyed by the terminology, he calls everything "training". But I'm not going to the Olympics.
Small size (for "navigation")
When working with a mobile phone (for route planning), it can fully navigate
Long battery life
Mobile and PC applications.
Sync with Strava and Komoot
Control by buttons
In Czech (although sometimes with errors)
Displays notifications from your phone (calls, sms, whatsapp and signal). It's just pictures and smiley faces.
Great configuration possibilities.
Very good visibility even in direct sunlight.
As I approach a turn, it could be a bit more "un-zoomed" so I can see where to go sooner.
When using a pre-set route, it cannot recalculate when I exit it (this does not apply to the "click to map and go" style of navigation, it can do it there)
It can't show the elevation profile in front of you, even in the case of navigation (just what it already was).

I recommend the version with the HR sensor, it costs a little more and has a better quality mount. Or a full sensor set, but there you need to pay a few hundred extra.
Lower price compared to Garmin
Intuitive control
Good button sensitivity. Easy to operate even when driving with gloves on.
Data on Sigma Cloud
Mobile and PC applications
A bit brief instructions, I was groping at times, but in the end I hope I managed to set everything up as I like it.
Harder to access the power button, but it's not needed while driving anyway, so at least it's not in the way: )
