"Ordered the refurbished unit and the screen is sharp and bright in daylight. I've been using it daily for about two weeks now. Runs a touch small but nothing a size up didn't fix. Exactly what I needed."

"Picked the gray model and it heats up fast and evenly. It's been on my nightstand since it arrived. Packaging tape was loose on one end, product was fine. I'm in Indianapolis, IN. Couldn't ask for more at this price."
