The Robo Shark Brigamo 444 I got left free for testing. The package came in a hard plastic shell that I had to cut only. Then I searched a long time for a user manual and found this not unfortunately. In the Amazon reviews I read that it is in the hard plastic cover. Unfortunately, this manual is only available in English and Chinese. But since I am familiar with RC vehicles, this was not very difficult. First, I have inserted 4 AA batteries in the remote control and then charged the fish on the remote control. Then I have the fish (thank goodness alone, without joyful children's eyes) tried in the bathtub. Here came the disillusionment quickly. This fish can be absolutely not steer precisely. It is a glide in the bathtub and the fish react very delayed. Has he come to the Badewannnenrand times, he is stuck there. The "reverse gear" at all does not go.
When my 4 year old son this remote-controlled fish would (with the abysmal steering) provide only for frustration, so this toy was disabled equal discarded.
I hope my review was helpful to you and help you to make the right purchasing decision.
