If you follow the procedures as stated it will make you happy. It takes some work but in the end it is a good product. In my cas there were streaks of yellow but this is residue and will come off with the degreaser. Good product!

I used this to repair peeling concrete stains on an interior floor finished with urethane. The challenge was to match the random nature of 2 mixed colors. Had previously used a concrete paint which looked like paint with no color depth. This stain had color depth and looked like it was part of the concrete and not just paint on top. I only used one color, but will order a second color and see if I can layer it to more closely match the original. The degreaser and cleaner helps get uniform color. I used a brick chisel to scrape the surface making the concrete more receptive to taking the color. Haven't finished with the urethane yet, but would expect an even deeper color effect. Overall I was surprisingly pleased. Watch the vendor video.

The acid stain it self was very easy to apply. I bought the sprayer, but was able to apply it (I don't recommend this way, but it worked great) with a painting edger. The edger was originally just to do the edges, but then I realized that I could just pour the stain on the concrete and spread it with the edger. It worked for me.
I will probably stain the outside concrete slab next, but will make sure to have the correct sprayer to make it easier.
The cleaning was a bit more difficult than I thought, but not too horrible. Just very time consuming.
