Tinitell is water resistant (splash resistant), but not waterproof. Therefore it should not be used underwater. This means that it can stand splashes of water, but it cannot be immersed into the water.
Tinitell loves a day full of playing and fun in the sun just as much as you do, but too much water doesn't make for a happy talking Tinitell. So, when you go to the beach make sure your kid doesn't swim with the Tinitell on, as this will damage the device.
Please don't use Tinitell in the water.
