If you like to read by the pool or at the beach, the 2021 Kindle Paperwhite remains one of the best e-readers available despite its age. That’s because, unlike Amazon’s latest entry-level Kindle, the last-gen Paperwhite is waterproof. And now through June 14th (or while supplies last), it’s on sale at Woot with ads, 16GB of storage, and a 90-day Woot warranty for $99.99, which is $40 off its original price.

Despite being a few years old, Amazon’s last-gen Paperwhite offers nearly all the features that make the current model our favorite e-reader for those who primarily read Kindle books. It features a sharp 300ppi display and an adjustable warm front light, which makes reading at night more comfortable. Battery life is also excellent, often allowing you to eke out months of use on a single charge before you need to top it off via USB-C.

The latest Paperwhite offers slightly better performance, battery life, and a slightly larger seven-inch display, but it also costs $159.99. Unless those upgrades matter to you, the older model remains a terrific value. The 2021 model is still snappy enough for most uses, and its 6.8-inch display remains spacious, especially compared to the base Kindle.
