Just seems too fragile for my taste. I travel and sometimes my Bro or my Daughter watch my fish. I'd be crushed if something happened the few days I may be gone. I'd have to call in a Emergency tank service. 
I'd have my wife do it, but she has her hands full with the 2 Kids, 2 Dogs, 2 Cats, 4 Tanks, and a Full 50 Hour work week.
