My 2 favorite products that improved my life: Kindle Wahl clippers Best money spent.
Wahl clippers are unreasonably good. No other brand comes close. As for an e-reader I'd choose a Kobo. You can copy the books to your computer and decrypt them so you will never lose access to them. I'm not sure you can do that with a Kindle.
I'm using Calibre to load books to my Kindle works well.
Ok that is good to hear.
