The Kindle Paperwhite is my favorite E Ink reader right now (and on sale for Prime Day)

Amazon's 12th-generation Kindle Paperwhite Signature Edition offers up to three months of battery life and fast page turns. Right now, it's on sale for $149.

• The Kindle Paperwhite Signature Edition is on sale for $149.
• I've been testing the Kindle Paperwhite Signature Edition, which features the fastest performance yet and up to 12 weeks of battery life; alternatively, the 16 GB Kindle Paperwhite is available for $125.
• Remember that Amazon's promise of up to 12 weeks of battery life assumes 30 minutes of daily use with wireless off.
