Useless product and terrible customer service …
I ordered a 3 in 1 filter plug which was advertised as suitable for domestic sinks. It is not useable for UK domestic sinks. The cost doubled between purchasing and money taken by PayPal. I attempted to cancel my order but was assured I would love it. I have contacted the company three times for a refund and information about how to return the useless item, with no response. Do not buy anything from them.
