beautiful and sleek/simple with lovely calm bubbling ---when you eventually set it up. Maybe i was unlucky but getting the pump to connect to the tube and settle in the water to work - and without vibrating - was a challenge. And I have tiny hands.  Another review mentioned the tube was too short-- there IS a way to get the short tube to work it just takes a bit of trial and error.  And thats a bit nerve wracking when you are aware one small wrong move and the whole thing will shatter.
