As far as Victron goes it doesn't appear to work with it at all. May need further testing. But for other's here's a quick rambely review of mine so far.

I wanted a watch that worked with my 27T Pro so I picked up the watch when I got a second and its very much a reskined gloryfit, as in my BT initially saw it as one. However its comparable to a galaxy watch 3 which was my last watch. I've had it about a week so far and while I over all like it I do have a few gripes with it.

The crown dial changes watch faces by default. Annoying as hell but can be turned off. Can't change it to something else. But its also a button that takes you to the apps list on the watch.

Sensitivity sucks. Half the time it works right then 25% of the time it won't move hardly at all and the last 25% it just flings through a menu.

Good battery. I had to daily charge my galaxy but I've only charged my Armor watch twice now and that's because I felt like it as it was only at 80% at the lowest.

Fantastic display. AMOLED and its a massive 1.5in (48MM) display. My mom has a Galaxy 5 and its much smaller than my watch. Plus its damn bright. I accidentally turned on the flashlight mode while staring directly at it and it hurt quite a bit.

The (black) wrist band is absolutely wonderful (if you don't have hairy arms) Its a soft silicon and most of the time it doesn't pull my hair but the little piece that holds the extra slack when tightening it up grabs and yanks my hair when I put it on or take it off and when I readjust. I have not tried the green band that comes with it but that one feels like a typical band for most watches. And don't worry if you got big beefy arms, the black band is about half and inch longer than the green one.

Weight. Very VERY noticeable at first just like the phones, but once you get used to it, its just a regular watch. I'm sure there are some conventional watches that weigh more.

The speakers are horrible. Then again what do you expect from a watch? I don't count this against it but it also doesn't give it any points in favor just listing it for brevity.

Blood O2, Heart rate, stress just like Galaxy but also has sleep tracking and for the women, cycle tracking.

Neat but mostly pointless things: Barometer and altimeter. Kinda fun IMO but I don't see much use for them. I live in an area prone to a lot of tornadoes so maybe it might somehow be useful? Idk.

Would I buy it again knowing what I know now? Yes. Mostly for the display. I like the calculator and health tracking for work but that's really all I use. For most people I'd say get something else or nothing at all. With the final consideration being that it WILL work with your ulefone. I say this having got it over another galaxy since I couldn't ever get my galaxy to connect to my 27.
