Nemo Underwater Drone with 4K UHD Camera and LED Fill Light, Aquarobotman ROV Drones for Marine Video, Fish Finder, Fishing Camcorder, RC Submarine Robot Toy

I bought my nemo underwater drone used from amazon. The youtube reviews i watched was promising & i liked the long tethered cable that came with the drone. When I saw a used one come available on amazon, i jumped at the opportunity to make the purchase. The drone new is $1,800. I bought it used for about $1,000. Bad mistake on my part. When I got the drone, it was missing a battery for the wifi station. You can't use the drone without the wifi station. Amazon offered to refund the money but that was not what I wanted. They would not or could not send me the missing battery. I bought the drone because I thought I came across a deal on a used one. I ended up having to order the wifi battery for $50. When the battery came in, I was finally able to start using the drone.The app was not available on google play and the QR code that came with the instructions would not load. You'll have to go to the website to download the app. When you find the app and began to download the app, you'll get a warning that this app maybe a risky app and the google does not recommend downloading the app. Makes you leary about downloading an app from China and giving the app access to your phone in order to use the drone. Well, i downloaded the app anyways because I've already spent over $1,000 plus the $50 and time waiting on the battery.After finally getting to use the drone, i was excited and happy with the maneuverability of the drone. That excitement didnt last very long after I took the battery out of the drone and saw that water had gotten in the battery itself. The battery that came with the drone was not properly sealed. I could hear the water swishing around in the battery. I have tried to dry out the battery for 2 weeks now. The battery is still dead and won't charge. It will cost $200 to buy a replacement battery. Im frustrated and afraid to spend anymore money on this drone because I'm not sure what else could be wrong with the drone. Huge regret with this purchase. Wish Amazon or the aquarobotman would make this right and send me something that works. FRUSTRATING!!-Binh

I used this Nemo to record kids' behavior underwater. You couldn't imagine that such little kids are also into it quickly. But what you need to note is that you gotta pitch drone and move it forward when you want to submerge it.

Do not disturb the oceans and lakes any more than they already have.

I'd love to give this more than one star, however, for almost two days now there is no access to an app to operate the drone either on the play stores or their website. Emails have gone unreturned and messages have gone unreturned. I'd be happy to update the rating if this issues is resolved. Until then, it's worthless......

My drone had some calibration issues. Aquarobotman service stayed in touch with me, guiding thru procedures but still a problem. Decided to send me another. Beautiful camera. And service from Aquarobotman is second to none. Looking forward to my new drone. I know it will be a good time.
