Thanks God for the internet and thanks for the service like this - proffessional solution on time.

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.

The downloaded quality was as good as the orignial

This is a great and complete Service Manual for the Sharp GF8585HB. Giving full and detailed technical insight. Good to find these manuals online.

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
