PIL is desirable to specify the color of the proposed reservoir and ability - not visible either on photosynthesis ... I have a yellow coffee, now with a rather bluish tank, and large capacity, which makes it look like a "turtle" ... But it is not very serious, Except for purists a cooking matching set ... I'm happy to refill my coffee, which I really like qualities, and that is not the first: I also had the beautiful red and black. And 12 and the practical delivery in a local shop, so good. The funniest thing is that my account is still not charged the amount of the purchase, while I took possession there 4 days ... So great security !! So some overall satisfaction. Thank you to all.
