For those who do tiling using porcelain tile, which is just about anyone now, most of the thinsets work fine. However, when tiling on a surface that does not absorb water using porcelain tile can be a real pain. Normal thinsets take forever to harden, since there is nowhere for the moisture in the thinset to escape. That is where this thinset excels. It seems to be mostly glue, and when it hardens that tile is very much adhered to the surface it is on.
That leads to the one problem I have found, which is that it does not act like a normal thinset. Normally, if the tile isn't level you tap on the high corner and the tile adjusts with the opposite corner rising. At least for me, when you do that with this thinset the entire tile sinks. Very important to have your bed of thinset level, or else adjust by back-buttering the tile prior to setting. The other problem is that it flows easily and is not very forgiving, and a complete mess if you have to lift a tile to add a little thinset to raise it up. As much as using a drier mixture would seem to help, I found it made it even harder to create a flat floor, and with the amount of adhesive in it, it seemed much less sticky.
The compromise I came up with is to take this thinset and add it to Home Depot's marble and granite thinset (by itself will take days to harden if using porcelain on aged concrete) in about a 50/50 mixture, or a bit less on the marble and granite thinset. The granite thinset has ample sand that provides body, and the porcelain thinset has ample adhesive. Together they should be ready for light traffic the next morning, and if you want to make certain I've used a heat gun to lightly warm the tiles (I keep it 1-2 inches from the surface and slowly move it around the tile). They always are ready the next day. I've never, ever had a tile pop using this thinset. Another alternative could be to simply add fine sand to this thiset, but I have not tried it and I have no idea how it would change the working and adhesive qualities.
A last comment is that this does not have the pot life of other thinsets. Due to its vast amount of adhesive it acts more like hot mud does in drywall work. Don't think you can pour some water on the top and cover the pot and come back later and be able to use it. It will be mostly hardened, and the batch I tried remixing (not a pleasant task) did not have very good drying properties, but the tiles I used it on didn't pop when finally dry.

Rated 5.0 out of 5.0 by Micki Great stuff
I liked being able to measure out only what I needed to mix for the area I was working on. I figured out how much water I needed per cup of mix so my mortar was consistant. Really liked this stuff.

This product was used for my first time tiling a floor. The finished product looks great. I will be using it as I plan to tile two additional bathrooms and a laundry room.

Perfect for laying tile. Also great for leveling a floor while tiling.
I had a very unlevel floor that required 2X the normal application of thin-set. Excellent product.
