The performance of the product will be tested over time, but there is no doubt. A sharply negative reaction is the lack of a power cable from USB, only from the cigarette lighter. USB is specially placed behind the rearview mirror and the old device had a corresponding power cable - now you have to buy it separately. But at the same time, its power parameters are not even indicated in the instructions in order to simplify the search and purchase of the appropriate cable. The problem with the warranty attached in the photo. The manufacturer declares that "The device is not subject to free service if" and p. 1 ". the warranty card is incorrectly filled out, the date of sale is not indicated, the seller's seal is missing." The photo shows the lack of filling out the warranty card. If, nevertheless, only a check is enough for warranty service, then why separately prescribe the absence of a guarantee under such conditions.
