Efficient service, but disappointed with the print quality. More appropriate for printing where hi-resolution images aren't needed. Your files are uploaded in PDF format and even if you upload in hi-res format, they are converted into PDF. My original, uploaded images were pin sharp, but when printed, they are of average quality, certainly not photo quality. I'd use the service again for text based printing, but will look elsewhere for photo-quality printing. I chose the highest weight of paper and colour printing, but these still weren't to my satisfaction.
