The question of whether the Mobius is the "best" dash cam doesn't quite hit the mark and kind of misses the true essence of what the Mobius is all about. What it is in reality is the "only".
The Mobius is a seminal, highly influential product that pioneered and established the category of action/dash cams we now know as "matchbox" style cameras.
As such, it is the "only" dash camera on the market that allows the user to use a battery OR a super-capacitor and switch between them at will. And it is the "only" dash camera that provides the user with an inexpensive easy to replace plug-and-play battery.
The Mobius is the "only" dash camera that offers a choice of lens focal lengths via easy to install and replace modules. The Mobius is the "only" camera to offer lenses that are designed so that the user can easily refocus and lock the lens in place. This unique feature even allows for macro work. And Mobius has gone to great lengths to supply lenses of the finest optical quality and in fact, even after four years on the market Mobius has recently introduced new lens options that feature enhanced optical correction, greater flatness of field, greater flare control and overall improved performance.
It is the "only" camera that provides the user with such a vast level of advanced controls over exposure, contrast, saturation, color correction, sharpness, bit rate, FOV, frame rate, resolution, video file type, multiple image mode selections on the fly and more.
Mobius is the "only" camera manufacturer that supplies a wide range of spare parts for replacement and customization.
And the Mobius 1 is also the smallest (dash) camera of its type on the market.
As someone who has been involved with dash cams for over 7 years now and has had personal experience with dozens of them, many in all kinds of extreme long term conditions I can categorically state that the Mobius is hands down the most reliable, durable and versatile camera on the market, PERIOD!
The Mobius was introduced over four years ago and even now, for daytime performance it will match and often exceed the daytime video performance of virtually any camera on the market that records in 1080p/30.
Perhaps it comes down to one's personal definition of the word "Best"?
Although widely imitated, some with newer, more advanced imaging technology and other features, there is to date, literally NOTHING on the market quite like the original Mobius 1 camera. It is unfortunate that the Mobius 2 turned out to be such an abject failure but hopefully its very gifted developer will bounce back with a newer model that will carry forward the heritage of the original; a true "classic" in its own right .
