Delivery promptly and reliably, price / performance, "OK"

Since this is already the second drone (the first is unfortunately landed in the water), I can say that this experientially is very good for beginners and advanced is a nice pastime.
They responded, especially in the control mode 2, very direct and to fly well even in light winds. The reach of the remote control could be slightly larger, but is still acceptable. The looping function is indeed a nice gimmick but only an extremely fast rotation around the horizontal axis.
The camera offers a mediocre picture. For a brief presentation of his flying skills (eg a smartphone) but perfectly adequate. During demonstrations to larger monitors or TV's the picture will very quickly spongy and you see problems in white balance of the camera. The photo function is poor and recalls the results of the very first camera phone.
The battery lasts for 8-12 minutes depending on the load and flight time is after a charging time of about 30-45 minutes ready for use again.
Overall, a good price / performance ratio.
