Used it more or less exclusively since Juli/August on the road - maybe 500km.
Would not change my previous good review; recognition is good (just watched a new video from gplama, he explained, that all Radars have this issue of detecting cars that stroll behind you). Very few false positives (One narrow metal bridge in 1/3 times gives one a false positives). Sometimes the distance is very good, like the dot on the Wahoo is not even visible (>130m or so), sometimes the warning comes a little late (<100m). As I have no back-cam I cannot say what's the factors are, such as curves, speed differential, road furniture etc.
Very light (50g + 28g mount), didn't use their app in the last 2 months, so I have no recollection of it - but surely it's not the best part, as kbernstein mentioned.
Also the price is very good for this package I would say.
