Best Purchase!!

Best thing I ever purchased. I have a lot of people in my family using one shower. This helps keep me from expensive plumbing bills. I use it every other week instead once monthly. Keeps the shower drain flowing good as new!

It works

I was having problems with my AC unit, water kept dripping from it. Tried different products to unplug the drainer, but didn't work. My AC guy recommended this product, and it actually works!
