Works fine
This product works fine for me. Level out perfectly. Add one and a quarter gallon of water per bag. It won't dry as fast because of the extra water so check the weather and plan accordingly.

Works just fine
I had a 10x7 corner of my basement that was slightly dipped (3/4") and I needed to level it. It took me about five and a half bags. The product worked as advertised. I might suggest the directions should be changed to one and a quarter to one and a third gallons of water per bag. It needs to have a liquidy consistency and then poured so that it spreads and levels itself. I believe the folks that were complaining stuck to the directions and it was just too thick.
Make sure you use a drill and a mixer tool to get a good mix. I made the rookie mistake of using my DeWalt drill with two batteries. Quickly realized I was going to use them up so I did the initial heavy mixing with a slab of wooden flooring. I then used the mixer to do the final blend. That worked like a charm and I poured and backed up, poured and backed up.

PRO-Select Self-Leveling Underlayment Did NOT self-level
Our project required leveling an area in preparation to install a shower pan and some other tile work. We calculated just under two bags for the job. After following the directions on this packaging we have a floor that is way off level. I am very disappointed...

Doesn't work - not self-leveling - overpriced garbage
As many others noted, it's too thick and doesn't level. I have worked with concrete, stucco and other Cementous products for a long time and know what I am doing. Followed the guidelines to the letter. Have used self-leveling (different product - don't remember) few years back with no problem. This product simply doesn't work and will ruin your day. See the attached picture.
The company simply responds to all the negative reviews "I am sorry" and then points to instructions assuming everybody is stupid. If so many customers have issues then there is something wrong with the product. They should be refunding instead of just saying "sorry".
Huge waste of money and time. Will take the bags to Home Depot and talk to a manager about the refund and, I assume they will act honorably.

Good product although they all leveled a little differently and we mix all 10 bags the same way. A couple of seams but after we put down a concrete water base dye it hid the imperfections well.

Don’t believe the haters
This was so easy to use. If you mix this correctly and pour it quickly you will have no issues. Use a good drill and a solid egg beater to make a mixture with a milkshake consistency. We poured 5 bags to fill a sagging area and it took about 20 minutes. Make sure to use the concrete prep.

This product did not work as advertised -- it was far too thick and difficult to spread, and it did not self-level at all. I was extremely careful and followed the instructions on the bag exactly: put exactly 1 gallon of cool water in bucket, slowly poured in powder while mixing, mixed 3 minutes with egg beater style concrete paddle on a drill, poured on cool, cleaned, primed concrete floor -- and it just didn't work. The end result is that my floor is far worse than before.
The as-mixed consistency was similar to regular concrete, but with a very short working time. It was extremely difficult to push the concrete around. The promotional video on HomeDepot.com shows it spreading around like liquid, but that was not the case at all; it was extremely thick and heavy.
In my photo, the back part of the room is what my wife and I were able to MANUALLY smooth out before the mixture set up too much to work with. In the rest of the floor, we roughly spread it out by grueling labor, but it was DIFFICULT because it wanted to clump up like a paste, not run like a liquid. Even on my hands and knees spreading with a 2x4, I was unable to push the mixture any thinner than 1/8", even though the description on the Home Depot website claims 1/25" minimum thickness. The light color at the doorway was the result of me throwing some extra water on top of it at the end just to see if it made it more workable (answer: no), since I already knew the floor was ruined anyway.
Reading other reviews, it sounds like the quality of this product is inconsistent. It works for some, but many others have the same experience I did. Do yourself a favor and DO NOT BUY THIS PRODUCT -- it's not worth the risk.

Sets Really fast - and you need more water
Followed the instructions to the letter, cool water, three minutes of mixing with a proper paddle and an industrial mixing drill. 4quarts water/bag.
Firstly, you absolutely want to use at least 5 or 5.5 quarts or the product will not level itself and will get ripples with any drag trowl. It also hardens much faster than 10 minutes. Within about 5 minutes the base of the pour will already be a sediment like mud and will cause any trowlwork to create ripples.
To cover a 350~sqft room I needed about 10-11 bags and it was still pretty thin coverage, about 1/8 - 1/4 inches. Unfortunately after spending all the money and doing all the work, the floor definitely isn't flat and it was apparent even when very wet that ripples were present throughout the room .

We are sorry to hear this. It is important not to over water a cementitious material as it could cause bleeding (unmixed water rising to the surface and causing streaking).
