I personally have the Corsair Scimitar which I like quite a bit but I had to get used to how to hold it. I honestly think that if I were shopping again today I would just go with the Naga. I think that the Naga is a “buy once, cry once” type of purchase. Mice with 6+ side buttons is just a really sparse product category and if you can manage you should try to get a few of these mice in hand and choose based on comfort

Edit: I specifically chose a wired mouse. The battery in my old Naga was so heavy that I ended up taking it out and just using it wired anyways. If you don’t need to be un-tethered, I would avoid wireless but again, that’s personal preference

If you add an individual book, and select None* for the metadata profile, only that book will show up under the author when it’s added. If you want other books for that author added, choose an appropriate metadata profile. Note that None does not apply any metadata filters and you may get unwanted foreign editions. To work around these create a metadata profile as prescribed in the faq
