The quality of the slide conversion was fine. However their Project Manager and I had agreed on a numbering system for the slides so that I could easily refile them. (I had thousands of slides). They then proceeded to not use the numbering system mixing slides from different time periods in large batches. They volunteered to "fix" the problem but at additional cost to me. I turned this offer down. It was unlikely that they could have fixed the problem since some of the original slides had been jumbled. I had to sort and numbered each digital slide. I also believe that some slides were lost. I have many more negatives and photos to digitize but I will be using a different firm.
