The Rebel Cactus Play has a waterproof protection degree of IPX7. This means that it can be submerged up to 1 meter in water for 30 minutes. So, you don’t have to take your Rebel Cactus off for everyday things like washing your hands, taking a shower, playing outside in the rain or splashing in the waves at the beach; but you can’t go swimming at a depth of more than 1 meter.

Unfortunately, this means that any water damage due to submerging the smartwatch for more than 30 minutes or at a depth of more than 1 meter is not covered under the warranty. But, if you act quickly you can possibly still save your smartwatch.

Turn off your Rebel Cactus as soon as possible!

Take a look and see how much water got in the watch. The more water that got in, the higher chance that it’s been damaged. Dry the watch off with a towel or cloth as quickly as you can and don’t turn it on, not even to check if it’s working. Make sure to leave the smartwatch turned off!

Rice method

Grab a plastic sandwich bag or a bowl and fill it with dry rice. Make sure your smartwatch is turned off and put it in the bag and shake it a bit so it’s completely submerged in the rice. Now find a safe dry place to put it and leave the bag or bowl with the rice and your phone for a few days (at least 60 hours) to dry out. afterwards, connect your Rebel Cactus to the charger and see if it works. Fingers crossed!!

An ounce of prevention is worth a pound of cure!
