Easy to use and does a fantastic job. HIGHLY RECOMMENDED.
This is the best product I have found for maintaining clean sink and shower drains. No need for harsh chemicals just to maintain clean pipes. I have not noticed a smell nor odor like harsh cleaning products have. Every few weeks, before taking a shower, I often pour the recommended amount down the shower/bath drain. I then use the toilet, shave, etc. It says to leave in for 15 minutes before flushing with warm water so I just plan accordingly. My shower drain was running very slowly so I started using this. After 4 times over a month period, everything was cleared and running smoothly. I now use it every few weeks to maintain the shower/bath drain. Container makes it easy to open and pour without any fuss or mess. Great value for the money. A fraction of the cost of some other brands but works just as well. I get the case of 8 to save on costs and so I make sure to have them on hand by each sink and shower/bath. I am extremely happy with this product. HIGHLY RECOMMENDED

WORKS -- all that matters
Zep is my 'go to' for a clogged toilet. Might not work on first try ... or second ... even third ... BUT it eventually works and isn't as 'messy' or gross as using a snake. ~half bottle, 12 hour wait, HOT water chaser for 15 minutes ... flush *use when the house has multiple toilets because the clogged toilet will be unavailable **IF you need immediate results, use a snake or call a plumber

Works pretty well
I used it in a drain of a very old garbage disposal. We did end up replacing the disposal anyway, but this stuff mostly fixed the slow drain.

BAD REVIEWS, BECAUSE CUSTOMER NOT USEING CORRECTLY
THIS IS NOT A CLOG REMOVER..ITS ADDED TO YOUR SYSTEM FOR PIPES CLEANED OUT BULID UP OVER TIME.. IT HAS ENZYMES TO BREAK DOWN AND KEEPS PIPES CLEAN.. ITS A TREATMENT OVER TIME WORKS EXCELLLENT.. RUN OR ADD HOT WATER, THEN ADD TWO CUPS ,YES TWO CUPS,THEN ADD A ONE CUP OF HOT WATER..TO WASH OUT OF TRAP.. LET IN SET FOR AROUND 8 HOURS FOR BEST RESULTS.. DO ONCE A MONTH...

Drain cleaner
No that’s all I can say didn’t really work but had a pleasant smell. Also did some looking and can’t go too much on what the internet or Dr Google say but you need a good rinse on the pipes so it doesn’t “sit” in the pee trap.

Takes care of drain gnats!
Works well and doesn’t smell horrible like most other drain/pipe cleaners. Easy to use as well. We had issues with small drain gnats but this took care of that problem. We haven’t seen one since we started using this.
