I was a key operator at my last job for the erytra. Fantastic instrument! It is incredibly quick, easy to understand, and I had very few errors with it's use. Also, TRUE stat function! We did have a problem with HLA antigens in our screen cells, that lead to a lot of unnecessary panels being run. After contacting Grifols, they quickly adjusted their donor screening process and the subsequent lots were clean. I was very satisfied with their customer service, and willingness to modify their products and software for their clients.
