Initially Top after few months the surprise

The pillows were initially perfect for sleeping.
Just a little bit with the water capacity to play it is pleasant.
After few months but already went the first pad broken. At night, woke up and half the mattress was wet.
The same happened also have 3 months later with the second pad. If you look in the opening, where to fill the pillow, then you will only see a thin plastic which the water is later ...

Shame
