I took a bit of a risk with Pubby, but it was totally worth it. I self-published three books via Amazon kdp in 2021. I had trouble getting reviews, and Pubby solved the problem. I read books on Pubby and review them on Amazon, receive snaps (like points) from Pubby for each book I review, and then use my snaps to get my books reviewed. I did the free trial and liked it so much that I bought the year membership, and am quite happy. One of my books has 28 reviews (26 were from Pubby authors), another has 17 and the other has 23. Some reviews are more detailed than others, so the quality of the reviews vary; however, that's true even when you don't use Pubby. I found that the majority of Pubby authors are honest and sincere and deliver quality reviews. Pubby customer service has been responsive to my inquiries and helpful.
