What we liked:
Everything. The features and attention to detail is superb, the best all round pump we have found with these features and quality. The low power usage. 5 year warranty on everything including the impeller - no other company offers a 5 year impeller warranty to our knowledge. Great value for money when considering the life span and reliability.

Less than ideal: Nothing, about as perfect as you can get.
