About the service it's very fast and reliable. About the manual the quality is high enough to read even the tiniest details on the wiring diagrams so you can't ask much more than that, let it alone for a manual of a product from 20 years ago. Thank you, very satisfied.
Everything was ok with the manual. If I have a small complaint, is that I ordered it during the weekend and I think you guys were closed. But I did receive it late Sunday. I will surely order from you again
