Unacceptable, after just the first use the battery broke, I am an electrician and I measured it, it charges and as soon as you try to play the voltage drops to half, it emptied once and never recharged again, cost of a new one from 15 euros....
I wouldn't have written a review but I did it for my little one who didn't enjoy it, so just so you know....

Very good gift for a child. I got it for my son and he played with it all the time when we went to the beach!!!

Quality construction. Very fast. Worth every cent! If it had a slightly bigger battery it would be perfect!!!

it's worth its money and it has taken a lot of beating from the little one and still works
if it lasts another year it will be top

The boat goes like a bullet, amazing jumps on small waves, great range, long battery life, easy handling, fast battery charging, comes with a few spare parts, it can become a submarine or flip over but it is easily restored with a button from the controller. It only works in water, when it's out, it doesn't operate for safety reasons. It has a range alert so it doesn't go too far and lose signal from the controller and a low battery alert. The battery lasts 20 to 30 minutes, it is rechargeable while the controller needs 4 large AAA batteries. It doesn't take on water and it doesn't seem like it will break easily. It needs to be washed with fresh water before storage. High speed and nice sharp turns, figure eights and jumps on the waves. Now, if my kids liked it, I don't know, they were behind me crying, 'Dad, let me have a turn' and things like that, I didn't hear them, I was hooked on the toy

The boat is really very good, fast and stable, it doesn't get affected by waves and provides great fun! However, after 5-6 uses, the two front lights broke, probably because they are not well sealed and were taking in water. Other than that, the product is worth its money.

I have bought countless remote-controlled vehicles since I was a child—cheap ones, expensive ones... cars, drones, machines, etc. This particular one is in the top 5 in terms of quality. I was amazed; it even has cooling for its motor, very high-quality construction, and it comes with spare parts. I first used it in a lake where it got tangled in big weeds, and after a long struggle, I managed to untangle it because it was powerful as a machine.
Update:
It was also tested in the sea with big waves and it didn’t even flinch... This tool is a bullet. Buy it with your eyes closed.

Very fast and quite a few minutes of play. However, in the first season I bought it and used it at the sea, even though I washed it thoroughly every time I took it out, it collected salt (probably) in the motor and it no longer works. What am I supposed to do with such a toy if I can't throw it in the sea?

I bought it to have fun with my friends, but I didn't expect it to be so good…!! First of all, it goes really fast, I threw it in the sea with wind and waves and it didn't have any issues, even when it flipped over, it immediately came back to its position on its own and kept going.. It has good range, nice handling, simple, nothing special for precision cutting, but it played well with the waves so I don't know much about that.. After a while, I stopped because, and I emphasize this, it requires a bit of caution; the propeller got caught in some nets and generally it needs clean sea or lake water, otherwise you will have similar issues, but today it passed a strong test, I believe, and it didn't take in any water inside the chamber..!!! Just a few drops on the caps, and after I finished, I put it in fresh water, cleaned it, and everything was fine!! It's worth the money… Check out the video I uploaded too!

It's good for the money speedboat. Its disadvantage is that it takes in a little water, and it needs attention.

Honest, fast, doesn't leak, 15 minutes of playtime.

Hasn't played again, for now I'm waiting for the service.

In the photo it showed red color and that's what I wanted, but it finally came blue and it doesn't have the range it promises

Very good construction that reaches very good speeds, both large and small, according to the user's desire. I have not noticed any sealing issues in the battery and motor compartment. Very good range as well. It also has a spare propeller. The duration of use at maximum speed is about 20 to 30 minutes from a full charge. It gives a warning for range and low battery so that the user can safely bring it back. It is worth every penny in my opinion!
