Rated 4.0 out of 5.0 by ReneeE I almost didn't try it!
I almost didn't try it because of some of the bad reviews. I had used a whole bottle of Drano Max on a laundry tub drain to no avail. So before calling a plumber, I decided to try Zep. I removed the trap so as to drain all water from the pipes, reassembled the pipes and poured In Zep drain opener to the top of drain. As the Zep would slowly go down the drain, I would add more. I eventually used the entire bottle. After waiting an hour, I filled the laundry tub half full of hot water. It didn't clear right away, but when I came back an hour later the pipes were cleared. Very satisfied!

so I poured this product into my clogged bathtub drain but, nothing happened. It took an whole night for the liquid to go into the drain and its still clogged.

Liquid in the kitchen sink would drain slowly over night, but would fill up when the water was turned on.
After pouring the entire jug down the kitchen sink drain over two days and waiting yet another day, it never cleared the clog.
A big waste of time and money.

Rated 4.0 out of 5.0 by Nusscular Works on Hair and Soap Scum
This is an Alkaline based drain cleaner (Bleach and Lye) which works well especially on sinks or shower drains which are clogged by hair and soap scum. This tends to be cheaper than other fancier foaming brands but I find it works just as well.
The only other product I have used which worked better was some dry pellet form drain cleaner which I used in the middle east. It literally smoked and boiled in the pipes. Not sure if you can legally buy that in the US but it may be worth a shot if this product does not work for you.

Rated 5.0 out of 5.0 by knowWhentoFold I used the whole thing
My kitchen drain flow slowed to a drool after I churned razor clam guts in the garbage disposer. I snaked the drain to 25 feet to no avail.
Not a plumber in the state was going to show up after 4 p.m. Friday, so I went to HD and bought this stuff. I poured in 24 oz (the bottle said 16) and retreated with the remaining 40 oz., following each treatment with 4 quarts of scalding hot water. The second treatment worked! I'm sure I saved at least $80 on a plumber weekend call. Whew! I'll be using Zep Drain Care monthly now.
The clams tasted extra good!

This worked VERY well and was only $6.
Used it to open my badly clogged shower drain. However,
1) I may have used more product than recommended on the instructions
2) After allowing it to sit for 20 minutes or so, I followed it by poring a pot of boiling HOT water down the drain.
$6 later, I have a well functioning drain!

Rated 1.0 out of 5.0 by Brooks9595 Poor Quality Product
After using a whole bottle in an attempt to clear my kitchen sink clog my sink remains clogged. So much for the guarantee to unclog drains in standing water. I can only hope they follow through with their advertisement and return what I paid for the product.

Rated 1.0 out of 5.0 by Smiley Did not work
I would not recommend this. I poured 1/4 bottle down my bathtub drain waiting about 25 min. and poured boiling hot water down the drain and the drain is still clogged. Tried again the following day another 1/4 bottle waiting about 40 min. and ran the hot water a while still nothing. Not sure why it worked for some, but it did nothing for my tub drain.
