Overall, the quality is appealing. The packaging good and the explanations ok. What was not OK, however, was the fact that the small peephole was leaking on the UV lamp and the plastic part in the end then even fell out. I could fix it with much gefrickelt but something simply annoying. The cleaning performance I think is very good for the size and power consumption. The entire filter unit can be easily cleaned. Please Note! You have to run either placed directly on the pond or attach a pipe to extend. Gibts in the plumbing department of each construction market.
