I love mine! I don't have any complaints. I no longer use it as a Phone due to the costs but I still use it as a tablet. I now have a $5 dumb phone for emergencies that Uncle Sam pays for. Tiny little thing!

I think the Fire Phone would have been successful had Amazon not tried to market against the iPhone which caused a ton of unnecessary reviews which made buyers wary.
It makes a great eReader and Media player and has a lot of storage! I like it better than my Kindle Fire 6 that collects dust.
