"Amazon devices are the top selling products on Amazon, and customers purchased more than twice as many Fire tablets than first quarter last year," Amazon Founder and CEO Jeff Bezos said in a statement. "Earlier this week, the $39 Fire TV Stick became the first product ever — from any manufacturer — to pass 100,000 customer reviews, including over 62,000 5 star reviews, also more than any other product ever sold on Amazon. Echo too is off to an incredible start, and we can't yet manage to keep it in stock despite all efforts. "
