Exactly what I needed.
Used to fill a crack on my front porch step, where the brick step meets the concrete porch. First cleaned the crack out with a wire brush. Second vacuumed the remaining dust and debris. Third applied masking tape to the outside of the area to be caulked for clean lines. Fourth applied with a standard caulk gun. Fifth pushed product into crack with my finger, recommend using nitrile gloves. Sixth added more product with caulk gun. Seventh smoothed to my liking with finger. Eighth waited thirty minutes and removed masking tape. A few weeks later I’m happy with the product, thick enough to fill in the crack very well, seems flexible, color is close enough to brick mortar for my liking.

This is the one
I used a different product last year that was more like a gritty concrete in a tube that did not survive the winter- cracked and fell out. I knew on the first application that this was the real deal- it comes out thick, levels well with a putty knife and stays put, even when filling vertical cracks in my front patio. I used backing for the large crack in my shed concrete pad and this filled in well and looks great. When dry it feels like it will flex and make it thru the seasons.

Super thin and settles deep into cracks
Would give it 5 stars, but, it’s a little too thin. Needs to be just a bit thicker to stop sepping so far down into cracks. I just needed about 1/4 inch settling down in crack before it starts to set. Oh well some people need it just the way it is for deeper crack I guess.

Blends well on concrete
Great stuff to fill in the cracks on my driveway. Easy to use and seems very durable.

Hard to dispense out of the tube.
Seems to work well, but is ridiculously difficult to dispense.

Bad from the start
I hope I got a bad batch, 2 of the 8 containers burst at the seams and made a horrible mess, after I waited a few days for it to finally dry it still has a really cheap feel and appearance when you walk over it. Not impressed, waiting for the rain and heat to peel it up so I can start over with another brand.
