Good hunt! My personal comments on this product as below :

Pros :

• Flying this drone can be enjoyable as it provides seven different intelligent following modes which give different flight conditions
• Everyone, even not professionals, can be accessible as it provides both app-based and traditional remote control
• It is foldable so it is convenient to carry for flying to any places

Cons :

• The maximum flight time is upto 22 minutes which I feel little short
• Quite expensive cost of U$947 (Halo Pro Bundle) and U$747 (Halo Drone)
