Joven user here. Mix feeling on it. My 1st Joven was spoilt because it seemed that the weter pressure from my house was quite high and I left the pump open so the internal circuits got wet and screwed the system.

I then got another unit of Joven from their technican (Brand new without pump) and everything seems ok now. Hope it can last for at least 3 years. If it gets spoil again, I will get a Panasonic.
