From performance, -built and video quality point of view vs price I must say only good words about this product. ( Have over 2 month )
The only drawback is long bracket mount arm, which doesnt do good, - - allows amplify a vibrations when driving over bumps, but because bracket base is standard to many popular chinese model,s then for 4-5 usd you can change it to other more practical bracket, so I dont see any big issue with it.
Of course questions asked ( as above ), - why silver ring, - why huge lens surrounding ?
For sure if starting developing from the scratch, then me also would prefer having lens at the very pottom part of body, this way upper part could be hidden under rearview mirror sunshade. But as Transcend was not a developer of this product, just used order fro ODM, ( I have a feeling Mio has some hand in this ), then it's totally understandable, - probably for "that" market needs.
