I had the GT2 before, the GT4 isn't a revolution, but I'm happy with my purchase nonetheless. Compared to the Runner I think there's still a good difference 🙂
I agree with mfamily. I previously had the Huawei Watch GT3 pro in titanium and am now mega happy with this one. Would buy the watch again in a heartbeat.
Definitely better, this watch is absolutely top. I would buy it again in a heartbeat. I use it a lot (with Oppo find x5 pro) and can only recommend it.
