Great for fixing Driveway, Walkway, and Patio cracks.
This stuff is great. I ordered it not really knowing what I was getting. I had two cracks that I needed to fix. The ease of use is incredible. Just sprinkle the material in like sand and lightly spray. That's it. I have fixed both small and wide cracks with no issue. It adheres to both smooth and rough surfaces. The size of the container allows you to fix multiple cracks. It is a great value for the money. The only issue you will have is if you are trying to fix a vertical surface. The particles will just fall out before they are wet so you should probably get another product.

Great product. Easy to use and it worked quite well.
I purchased a tube of goop from a different provider and was quite disappointed. It just seemed to "gum up" when I squeezed it out. Just didn't fill well. So I purchased this product to give it a try. Very happy with the way it worked. Easy to fill cracks and smooth then just spray some water on it and voila, you are done. Would definitely buy again.

Good product
Works well, used to fill a chip in my garage floor. It dries quickly and leaves a nice even finish. It adheres to the existing concrete well.

Easy application / minimal clean up
Easily application and served the purpose. I'll see after the winter how it holds up. Expected to be able to cover all the cracks in my driveway, but ran out of filler towards the end. Make sure to not submerge with your hose after applying.

Works okay, could be better
Works alright. Definitely fills the cracks in concrete, but couldn't seem to get it to cure properly since it was basically hard sand that could be swept off pretty easily. Followed all directions with no deviation. Could possibly be that you need to wait a lot longer when using it in a garage without direct sunlight. I would say it dries quickly, but once again, wasnt as solid as expected once dry time passed.

Solid product, easy to use, a bit grainy, blends well
This is a solid product, but I agree with some of the points made by others. It is a little grainy and it does not do fine cracks well. It does dry to be very durable and it blends in with existing concrete well. For those that are looking for finer powder to fill in small cracks and imperfections, consider using Rock-tite. It works well, but is whiter in color. I have a feeling that Rock-tite and this product could be mixed, but I haven't tried that yet .
