Rated 5.0 out of 5.0 by EnserNG Works Amazingly - for the right issues
It all depends upon the cause of the issue, folks. If you have roots or other things causing 'slowness' then there are other Zep products for those. Best of luck!!
Here is our experience:
We moved into a home in DC about three years, ago, (city water and sewer) and the previous owners had coat hangers and plungers near every drain.
After trying numerous things, we found this and, will be darned if it does not work like magic. Every 4-6 months, we treat the beginning-to-slow drains and they move to 100%. Not sure, exactly, the issue, but we keep hair and other debris from the lines, and this stuff keeps things moving, without issue.
This is not, really, intended for clogs, and the directions make it clear that you need to remove any hair or other solids, for this product.
Home Depot pricing is about half of that on Amazon, so worth it to grab from here.

Rated 1.0 out of 5.0 by GatorTom Zep Drain care powder--questionable value
The descriptions of this product as a grease-eating formula of enzymes and bacteria sounded great but I wanted to test it in a more controlled way besides pouring it down my sink. I browned a mixture of pork and ground beef then poured it off into a can--about 1/3rd cup worth of juices and grease. I mixed a teaspoon full of Zep powder with a quarter cup of hot water and added it into the can--stirring the whole mixture. Over night the grease congealed about 1/8th to 1/4th inch think over the liquid in the can. I left this for two days then broke up the grease 'wafter' to allow better access by the Zep since there had been no noticeable change in the amount of grease. After another two days there was still no evidence of any degreasing activity. I set the can in warm water on the stove and warmed until the grease again melted, added another half teaspoon of Zep powder, and set it back on the corner of the counter. Over night the grease again formed a grease wafer on top of the liquid which, when broken up, appeared to be the same amount as had been noted at the start. It has now been nearly two weeks since I started this process and there is still no evidence of any change in the amount, or consistency, of the collected grease. The can is obviously not like a drain but one would think that Zep would be even more effective where there is no running water to wash it away. If it works no better in the pipe it would seem to be of little value. I am seriously disappointed since the idea of grease eating bacteria in our modern age of biological science seemed entirely reasonable but this product does not appear to be an example. I'm letting the experiment run a while longer and will do a follow-up if anything changes but this does not seem to be a useful product.

I've seen little to no results using this. Have used as directed in bathroom, kitchen and basement sinks. Have used over several days (waiting overnight or at least 6 hours before running water), and can't say I see any difference. Water still going down slowly in all sinks.

I have used this product for years and it really is a great maintenance product for drains. It was highly recommended years ago by a very good Plumber.

Rated 1.0 out of 5.0 by Greg No impact on slow shower drain
Tried this product because of the appeal of the concept of enzymatic action. Followed the directions precisely, initally....warm water through slow shower drain first, then 1 pint warm water/1 scoop, then no use for 6+ hours (actually, no use for 24 hours), repeat 3 days. No impact. Then tried twice the volume.....2 pints/2 scoops, 3 days. No impact. Then tried triple the volume for 3 days. No impact. Then tried 2 scoops in 1 pint, twice the volume (i.e., 2 pints water with a total of 4 scoops) for 5 days. No impact. Used up the entire 18 oz canister. Very disappointing since this is really nothing more than a household shower drain, most likely clogged with hair/soap buildup.

Rated 5.0 out of 5.0 by ck0828 I LOVE THIS STUFF!!!!
I have tried so many things to get the smell out of my kitchen sink, garbage disposal and side sink. 8 years. Tried Everything. This is the one thing, if you follow directions properly, that has worked.
It's awesome. It stopped the sink from draining slow and the awful smell coming from the pipes is gone. I do have to do this periodically but that is expected and for the price you can't go wrong.

Rated 1.0 out of 5.0 by Brook607 You're better off using Baking Soda
This stuff made my slow bathtub drain even slower. I did the 3 consecutive day treatment, and it almost completely clogged up my drain. I most likely have a hair clog, and this product did something to make it worse. It isn't worth the money, and I suggest baking soda and vinegar to keep your drain clear. Baking soda is great for grease and oil, and it's so much cheaper. I do not recommend this product and will never buy it again.
