I have a Kobo e-reader (the model that’s closest to a Kindle Paperwhite) and I think it’s absolutely worth the investment. Similarly to Kindle in the US, my e-reader lets me connect to my library so I can borrow ebooks straight onto it for free!

You don’t need an e-reader to use the Kindle app or the Libby app (connects to your library and lets you borrow ebooks and audiobooks), but if screens bother your eyes then I think it’s worth the investment. The ~$120 price seems steep for a one-time purchase, but since books cost about $20-30 new (probably around $5-10 each including shipping if you buy them used?), it pays for itself quickly!
