Thank you for your feedback. Sorry to hear you're disappointed with the Green Genie Filter. This is one of the lower cost filters we sell, they definitely serve a purpose and lots of people buy these filters to replace the same models that no longer work, because they're so straightforward to use and a cost effective solution for smaller ponds. However, if you're unhappy with it we do accept any unused products returned to us for exchange or refund, so please contact customer.services@bradshawsdirect.co.uk and i'm sure we can find a suitable replacement for you. Thanks
