Review on Bio-Clean Ultimate Drain Cleaning Kit: All-Natural & 100% Guaranteed to Clean Drains, Septic Tanks, and Grease Traps! No Caustic Chemicals, Removes Fats, Oil, and Grease. Complete System Cleansing! by Gregory Castellanos

I poured quite a lot of trash down the tub drain to clean my daughter's and my long hair. The spiky plastic tool fixed most issues at once, and 5 uses (according to instructions) did the rest. I wanted to set a 30 day timer as a reminder, but there didn't seem to be a base to install the battery. I sent a question to their support team and received a friendly personal response 24 hours later explaining that I had to pull the base out of the bottom of the timer. Presto! Very glad I can stop messing around with other products. I will stick with it.
