I really only bought this because of the smoothing tool that works very well. It comes with a 1/8" radius on one end and closer to a 3/16-1/4" radius on the other. I suggest trimming the end to create a 45 degree bead instead of a radius. A radius that narrows towards zero means a weaker bond to the substrate and is more prone to chipping. The smoothing tool tip is a softer silicone that works well as a squeegee when you don't know how to apply the perfect bead of grout. The tip that goes into the tube had too big a radius and would have wasted a lot of material, so I didn't use it. I also didn't use a removal tool, so can't comment on that, but it looks like it would work fine without scratching. It also strangely comes with a pouch that the tools don't fit in. As for why it's included, I am not sure.
