the problem with the Insta cams as a cycling dash cam is battery life, ok its the highest quality you can record but they themselves only rate it at 75mins. most commutes are going to be in the roughly 30min range, 1hr per day, thats you having to recharge every day just to keep on top of it. plus processing of the files.
whereas Cycliq, certainly the 12 is nearer 10 hrs, without the light, more like half that for the 6, though weirdly the light uses less power than the 12. whilst the lights are handy, Id never rely on them as a sole light solution. But the audio beeps the cams give you,give you an idea of how battery life is going.
and certainly I find the cycliq setup to be far more fit and go than most cam solutions, which is ideal for commuting.
whilst it does have its flaws, theyre expensive, the lenses are far too easy to scratch, they can be prone to one off failures (suggesting QC isnt that great on them), though its worth highlighting where you place the 6, it gets an enourmous amount of spray,grit and grime chucked at it in a typical British weather environment, its not surprising they go a bit wrong sometimes.
and like Garmin they dont really have many competitors. there are lots of lower cost cameras out there but Ive always found the video quality worse, battery life is worse, the eco system of handling the camera, the files it produces and so on, is worse.
