Bests & Worsts Reviews from Amazon

This is my first Kindle. It worked fine for 3 days. On the 4th day, the screen froze. Tried resetting multiple times. Nothing worked. Still the same. The screen refreshes from time to time but doesn't work. It's been like that for 2 days now. Very disappointed. Contacted the support and they immediately suggested to replace the unit. Planning to return and get a refund.
