From the price to the design and right down to the spec sheet, the iStrong car reverse camera system is definitely identical to the Chuanganzhuo kit. That being said, you can actually choose either of the two especially if your main consideration is the price. There really isn’t much to differentiate these two products, leading us to think that it may come from only one manufacturer but is distributed by two different entities.
Whatever the case, you get the same features as the Chuanganzhuo. Perhaps the only difference is that the latter comes with only 1-year warranty while iStrong gives you 2 years.
