Poor quality duckbills. Open before first use, 2 Month old ones did a better job than these. Better off buying cheaper alternatives on Amazon.

It’s great that all the parts are sold on the website, they were dispatched and arrived quickly. I needed a new auction piece and it wasn’t clear that the suction discs included a plastic piece so I ordered a set of those as well unnecessarily.
