Je suis audiophile belge, électronicien et créateur d'enceintes acoustiques.
J'ai apprécié la qualité des documents fournis. Ils sont très lisibles, ils peuvent être agrandis sans problème et ils sont complets. Pour moi, c'est parfait. Pour cette qualité, je suis d'accord de payer. Et le système de paiement et d'envoi est simple. Merci, continuez comme cela.

The cover page was a little scary, very dark but readable. The remainder of the document was better copy and easily readable. Why would I give 5 Stars? (1) PRICE, (2) AUTHENTICITY, It was the real deal, filled with service information, including the specific information I required. (3) PRIVACY, I didn't start to get slammed with spam. (4) EASY TRANSACTION. Painless. (5) COMPLETE, I have found several manuals here, that I could find nowhere else. (6) I will be a repeat customer!

Well done!!! I found what I need to have, indeed!
Furthermore, due to my hobby is repairing vintage equipments, I added this web site in my desk toolbar because I have in mind to search further service manuals. Thanks a lot www.owner-manuals.com !
