WAYDOO Subnado Underwater Scooter

WAYDOO Subnado
Underwater Scooter

This item was acquired as a gift, but I am unable to use it effectively, so I am listing it for sale.
As shown in the images, the power turns on, and it can be reliably turned on/off and charged. However, its operation is quite unstable.
When I press the button on the handle, it doesn't move easily, and sometimes it starts moving after repeatedly pressing it several times.
It's possible that it may stop moving no matter how many times you press it.
Please purchase only if you understand and accept the above conditions.
Returns and cancellations will not be accepted under any circumstances.
No claims, no returns, please.

There are no major noticeable scratches or dirt, but there are signs of use. Please refrain from purchasing if you are concerned about minor scratches or dirt, or if you are sensitive about such things.
The box is not included. Accessories are limited to those shown in the images.
I will answer any questions you may have to the best of my ability.
