Herios Drain Foam Cleaner, Liquid Hair Drain Clog Remover & Cleaner Quick Foaming Toilet Cleaner, Clog Remover for Kitchen Drain, Sinks (500ml)

Very easy to use and works just as the pictures indicate. No english instructions so you have to follow the 4 small picts on the side of the can. The foam does cover and seems to penetrate into the plumbing pipes as claimed. We'll see how it works "long time". If it works as ZI hope, it will be a very attractive product as well as economical.

This product does not work for me at all. I followed the directions exactly like it says and nothing happens but the foam sits there. It doesn’t overflow out the sink or anything.
