@2000rpm bearing in mind the Mobius and JooVuu are fairy similar, what appeals about the Transcend 100? Simplicity?
Have your tried any of the more expensive Transcend models - 200; 220? No better?
We ran two DP100 cams in the rear of our cars for a couple of years and covered tens of thousands of miles. The adhesive mount stuck where a suction cup would fall off due to the heating wires.
In the couple of years the DP100 cams were in our cars, they covered tens of thousands of miles and neither of them did the slightest thing wrong - they are probably the most reliable cams we've had; 100.00% reliable.
Of course at some point their battery will fail and they won't be reliable unless they are disassembled and the battery replaced. I haven't opened a DP100 but some cams require considerable disassembly to get to the battery, followed by soldering.
They have recently been replaced by JooVuu X which is more compact, has a capacitor for improved heat tolerance, has many more mounting options, including photography adapters which have compatible 1/4" threads, and has video quality superior in every way (a step up at night, a step up in field of view, two steps up in ability to capture details such as plates).
There was also the plus point that the DP100 came with a 16GB memory card in the box (worth £5 and an extra cost for most cams) plus a two-year warranty where many other companies offer only one year or in some cases with the cheap Chinese stuff it's only three months.
Why not the DP200 or DP220?
Video quality of the 200 or 220 is not greatly improved over the 100.
The original (pre-2016) DP200 had a capacitor but apparently could only be relied upon to hold date/time for 3-4 days if unused (Mobius will hold it for twice that). For 2016 the DP200 was changed from capacitor to battery by the manufacturer.
The DP220 has additional features that add cost but don't add to the basic dashcam functionality of recording your drive. The DP220 sells for over £100 anyway.
