I am using this primarily to record the rear of the vehicle as I already have a dashcam for the forward view. The (optional extra, not supplied) SD card is required to be reformatted every 15 days is a hindrance to the ease of use, especially when one has to go through several steps from the "Menu" to find the formatting function. Perhaps the product should include an optional "Overwrite" function so that the card can be written over automatically without reformatting required. Since the user manual is in such small print and it is hard to read, perhaps a pdf version should be made available for users to download and print out in a larger font or for viewing on a computer screen. Anything to make a pretty good product become enjoyable to use rather than a chore.
