5 Stars
Awesome! Perfect product & service
I ordered the complete set together with the gage and din adapter. The reason is that I always have new buddies in my holidays in Asia and that I dont want to trust only buddies which I don't know. The delivery to Germany was made by DHL Express and was quick. The quality is amazing, I already made two tests on 18 meters without any problems. I want to say also thank you to christeen from the support team who was really friendly and answered always very quickly.
