I am really satisfied. It was ceap, easy and quick. Te owner manual is a full service book. I got what I expected. Thx
;
The service was good but it just a little late for the download. It seems that it needs to clear the payment but the payment was settled by paypal. As far as my concern, it should be able to download after the confirmation of sold.

Great quality manual, fast service, excellent seller... Thanks !!!
