I have a Kindle Paperwhite, my second one bought for me for Christmas a couple of years ago. I find it brilliant - non glare screen, one charge lasts me ages (at least a week if I read for a couple of hours a day) and it doesn't take hours to charge up fully. I have had a Kindle since the first model came out (the one where you had to click a button on the side to turn the page) and wouldn't be without it, particularly when I go on holiday.
I also subscribe to Kindle Unlimited as I am a voracious, fast reader and can read a book in a couple of hours when I'm in the mood! Plenty of choice and you can download up to ten books at a time, returning them as you read them so that you can download another.
