In the photos, they look nice. But when you hold them in your hands, NOT! It may have many accessories in the set like the spiral or the tape, but you realize that they are not of good quality and for large currents. You understand this immediately when you look at the power cable at the ends. The wires cut and rub easily. Also, the RCA cable at the ends of the plug, the little pins bend with just a touch! The plug at the ends gives the feeling that it is made of tin! It definitely isn't worth the money for me. I bought a Ground Zero for 8 euros more and installed it in my second car, and the difference in quality is chaotic. For 10-15 euros, it's worth it, but not for more. Go for something more quality.
