I bought it based on the reviews. I connected it myself, it connects easily, the trunk does not open, the alarms do not flash when it opens or closes. I have had it for 2 months, it responds to all presses. I had to buy a board to make the alarms flash. Time will tell; whichever other one I installed died after 6 months, so time will tell. I am updating after one year, the device works normally. I ordered a second one because I was very satisfied with the first. The first and the second are completely different; the second one has features for windows, trunk, alarms, everything. I don't know why this happened with the first one. 15.7.2025
