I’ve been listening to the “Destiny’s Crucible” series by Olan Thorensen. Currently on the 8th book “A Fearful Symmetry”.

It’s about a guy from earth that has been transported, by aliens, to another planet that happens to also have humans but their culture is at a much lower technology level(around what earth was in the 1600s). And it follows him as he adjusts to the culture, and carefully starts introducing innovations.

Whats a reputable source to compare ratings/reviews for these machines? Do you have any personal recommendations?
