Rated 5.0 out of 5.0 by AcePeters It is unlike any other brand. It's Fast & Super Hard setting results can be an advantage.
Concrete has small rocks + mortar dust (setting posts). Cement has finer pebbles + mortar dust (street work). Mortar consists of mostly fine dust (for filling in between bricks or setting patio slide doors into stucco for example). Rapid Set makes ALL 3 types, which harden Very Fast. The same learning curve is on all 3. But, I've used each in different situations & loved how great it's outcome was each time.
This Mortar from my experience has about a 20-35 minutes work time. Home Depot sells an additive package, which gives you an additional 20-30 minutes. As a result, projects are finished much faster than by using other brands. Rapid Set also cures at a Super High PSI rating, which makes my projects last many more years durability-wise (vs. less strong mortar becoming brittle & breaking up over time).
I've used this for small to medium projects (jobs that took 1/2 to 2 bags). I've found that making it in batches & using the additive works good. If I had to use a lot more bags, maybe some users might have a point (not sure). I like the long term extra durability this stuff gives... it's so strong you can make little ramps from floors to doorways that would ordinarily crack in short time with older brand stuff.

Rated 1.0 out of 5.0 by DJ Hardens so fast it is useless for all but smallest project
This product sets faster than 15 minutes. The bag sayssets in an hour. Once mixed, you have at most 7 minutes to work the mortar, at most. Ruined my cement mixer after being in it and hardening while mixing for less than 15 minutes. Set way too fast to use for a shower mortar base even though it says that is one of the uses stated on the bag. I will certainly never buy this product again.

Rated 4.0 out of 5.0 by rosif3r first time working with mortar - not a bad experience
Before I go into my experience with this product, I’m going to suggest that if you haven’t worked with something like this before (as was my case) you go watch a video like the one I’m going to link to, just so you have an idea of what the consistency of the mortar mix should look like for your desired application. There’s lots of links out there, but the one I found (and reference below) was done by a representative of RapidSet:
So, as you can see from the pictures, I had a couple of holes in my basement: a small one at the juncture of 2 walls and the floor, and another where the wall, floor, and stairs meet. You can’t tell from the pics, but the larger hole also extended a little under the bottom stair.
The mortar mix was pretty easy to work with. Obviously i used goggles and a face mask, to avoid getting the dust in eyes or mouth. And the drill mixer was key, especially as the mix got thicker. I initially started to try and measure based on the water:mix formula on the bag, but realized that the consistency was more important, so i just added more mix until it looked and felt right (going by what the video showed). And working with the mixed product was no chore. I double-gloved with nitrile gloves, hand scooped it into the holes and packed it in, then smoothed it with a small trowel. Since it’s a basement that doesn’t look so spiffy otherwise, i wasn’t too worried about a finished look, hence the slightly rough look in the “finished” picture”. Also, the after pic was taken about 24 hours after the “after” picture. I know there’s some part of that that looks still damp, but its not. The whole thing is rock hard and dry.
Also, the Installation Guide and Specification docs that are available on the product overview tab for this product are much easier to read over than trying to read the back of a 55# bag of mortar :-) If you’re someone like me that is not intimately familiar working with this stuff, a thorough read of the spec sheet was key.
So, yeah, all in all a good experience.

Rated 5.0 out of 5.0 by Mikkel1955 mixes well.
I used this motor for 3 different tasks on one project. In each case, it was easy to get the desired consistency.
The first was to grout under a threshold for the outside door to the basement. The floor under the door is poured concrete, so this worked out well. It compensated for the slop of the floor nicely. I also does a nice job of keeping water out.
The second task was to reset some bricks that had come loose during the project. The mortar easily mixed to a firm consistency, allowing easy adjusting of the bricks to match the adjacent bricks. It is doing a nice job of holding the bricks in place.
The third task was the hardest. I had to tuck point some of the bricks in the stairway leading up to the door. Here the consistency of the mix was critical to getting a good bead of concrete into the joint, and having it stay put as it set. The mix did a good job of adhering to the bricks, while still flowing nicely from the grout bag.
All in all, I am happy with the results I was able to achieve, especially as I don't have a lot of experience working with mortar, as compared to poured concrete.

Rated 2.0 out of 5.0 by Ohioguy Dries too quickly
I'm sure this is a great product if you are just pouring it somewhere but it is not ideal for repairing block basement mortar. It dries too quickly, so you have to mix more batches. You are better off using Quickcrete and saving yourself some money

Rated 3.0 out of 5.0 by constructador FAST setting. I mean FAST
I would recommend this product ONLY if you can work a bag in about 15 minutes. I mixed a bag and worked it as quickly as I could. I had to complete the first layer of my shower pan within 15 minutes because after that the mortar was SET and unworkable. I wouldn't use this unless you were just in some kind of a hurry. Sets too fast to make a nice finish...unless you are Speedy Gonzales.

Rated 3.0 out of 5.0 by frank Not smooth surface
I read the review and bought this one for my brick work, hoping it can stick bricks together and the bordering concrete (the trench was cut from existing concrete). However I can't get a smooth surface in between the bricks, and also between brick and border concrete. I think if the space is larger (like >2 inch) you can get a smooth surface only when the first time you apply after the mix, since it hardens very fast. I think that's because it has too many sand inside. So I think it can only be used under the bricks.

Rated 5.0 out of 5.0 by farmgirl95602 Smooth, Easy to Work With, Dries Fast
This mortar is smooth, easy to work with and dries fast.
I needed to re-mortar the lion to the pillar. The moss/mold had eaten away at the mortar (30+years) and the lion stayed there because of sheer weight. Any one who gave it a shove could have made Humpty Dumpty out of him.
He is now secure on his pillar hopefully for another 30+ years.
