This kindle is great! As an amateur surgeon I often find myself flicking through medical books on my Kindle Paperwhite as I operate. The thin yet durable design allows the Kindle to be held upright, pinched safely between the ribs of my patients for easy viewing while the waterproof casing allows the kindle to continue functioning no matter how soaked it gets resting partially inside a person. The adjustable font settings also allow for easy reading, even while a patient is struggling or screaming. 10/10. Would recommend to any amateur surgeon.
