Received an email today from Banggood which lists the Mobius dashcam at USD68.99. The Mobius and the SJ1000 are 2 of the most recommended dashcams for under $100 in the dashcamtalk store and it is cheaper than Mobius's own store which is selling it at USD79.95.
A detailed review of the unit can be found here:
Note I did find the same dashcam selling for the same price under their link for an eBay seller, so if you prefer eBay, that would work as well, but Banggood offers points with every purchase so that would be an advantage.
