Produit pour remplacer le même produit que j'avais abimé, rien a redire

very good. original

使いやすいです。

I bought these to make cleaning aquarium easier. They work better than I imagined. I liked them so much that I re-ordered them.

Fantastic product, easy to put on, very good quality of valves, easy to operate, no leaks. Good value for Money. Used that before for years and never had any issues with this so very happy customer again. Very easy to create special additional loop to add for example temporarily UV lamp to the system or Nitrate filters etc..... or just makes life easier when disconnecting external filters.
