Surprisingly good quality for such a low price...as far as where it sits in the car, my Nissan Tiida ciggy power supply is to one side of the handbrake and in certain lighting conditions the display is hard to read. Other than that, a good piece of kit!
This product is extremely good, specially at the price charged. I bought my first one a few years ago and it lasted around 5 years. I replaced it with the same, hope it lasts the same length of time.
