so will you recommend to purchase it? What was the battery life?
I am considering it over varia, as it is cheaper.
I would recommend it at this point. Looks great, good, firm mount, bright light - esp. compared to Magene.
Also connected with a person from them on WeChat about the German light situation - the blinking can be disabled already with an iGPSport head unit, but app option is on their road map (in Germany, it's forbidden that mounted lights blink at all - which this radar does)
I made a German video about it, comparing it to Magene L508.
Stationary warn range (bike not moving at the side of the road) is about 120m, but if you are moving it's a little bit more, more like 150m, even the "car" dot on my Wahoo is outside the lane when it gets red.
False positives almost none! I had like 1 in 300km now on an iron passenger bridge, Caveat: I am not riding a lot on roads though, prefer bike paths.
False negatives: nothing that stood out, of course there are "late" warnings when the cars are driving really fast (this is germany, so 120km/h on a road is kind of normal...). Also motorbikes had been warned, but with less distance.
