Hey,
I want to buy this month new car dvr.
Choosing between mobius and mini 0801.
I ended up with the same shortlist as you, mainly because my number one priority is the smallest, most discrete, dashcam that I could fit & forget without worry of it being noticed by opportunist thieves.
Ultimately I decided against the 0801, partly because I don't want anything fixed to the windscreen, as it attracts unwanted attention, even if the fixing is a small pad. Also, I didn't like the hardware variations, the firmware issues, the hypersensitivity to card specification &, after studying many, many clips I'm convinced that video quality is not quite as good as Mobius by day or by night, but especially at night.
Here's a couple of 'raw' video clips I've taken with the Mobius at the
lowest of it's 3 quality settings, using a 3 year old, unbranded, Class 4 card...

As you live in Estonia, you're not like likely to be troubled by Mobius heat issues for a while. If leaving the car parked out of the shade on hot summer days, it would be prudent to take the Mobius with you when you get out of the car, otherwise it's battery may fry if the interior's temperature exceeds about 47 degC.
Regular Mobius firmware updates will make it better & better over time. It's night video quality may further improve, as it's hardware spec is very similar to dashcams with currently slightly better performance, the difference being down to firmware.
You have a choice of two good quality, 7-element Japanese lenses. It's internal battery lasts 80 minutes between charges, so you have the option of using it's action cam capabilities if you feel the urge.
I've only had my Mobius a short while but, so far, it's been a hassle-free experience, & I still find it hard to believe that a camera the size of a small pack of TicTacs can produce such good quality video.
