Hi,
The other day I used my Pulse Interactive while I was showering, after that it did not turn on or shown any lights while charging.
2 days later after the company already sent me a replacement and told me I can keep the faulty one I tried to turn it on again and for my surprise it turned on. (for a minute at least then it powered off, now it’s on the charger and will see what happens)
I feel kind of bad for asking for a replacement, but at least now I have two. One for home and one for travel. 
To get to the discussion part of the topic, I’m just wondering what has happened? Kiiroo advertises this product as being fully waterproof and it’s okay to use it in the shower. Maybe it was the heat that the toy didn’t like?
