Perfect. The online ordering was easy and the download worked great. I'm very happy with my manual.
I'm so glad that I could make repairing procedures on my on since they are explained from A-Z in the manual. The price was good too! The company offers the manuals for such affordable price! I'm glad that I find out about this company so early..
