I ordered my A229 Pro Duo 4k about 2 weeks ago. I was astonished that the product arrived the very next day. I had it professionally installed by a local shop which also went very well.
Set up was easy although I initially had a little difficulty connecting to my Android phone - the directions could have been more thorough. Going through the menus to set up my preferences was straightforward.
I have downloaded a few clips and viewed on both my phone and my computer. Image quality is very good. License plate recognition was better than I expected during the daylight hours. Night shots were also better than expected although license plate recognition falls off in the dimmer light.
Overall, I am very happy with the product and the service I received from BlackBoxMyCar.
