Considering the price, I was a little scared. I had to fix my subwoofer which had two broken capacitor. So installation kit (arrived opened but complete) and functional heating iron. Preheat a long hair but it works. The pump makes a little "cheap" but it works well. We must have the hand. Fil sold. Relentless welding through the cutting edge. We can change dailleurs necessary. At the end of very happy with my purchase. After you have to see over time but troubleshooting is perfect and you find nothing else at this price. Thank you Amazon,
