It looks pretty much like the rest of the "probiotic" foods out there. I'm guessing you didn't read any of the info in the link that I posted, you really should.
Here's my personal review based only on my personal opinion from the info supplied by this company based in Singapore.
Sprulina itself may have a probiotic effect on fish (I believe that quality spirulina does) but it is not a probiotic as it is not a live organism when sold as dry fish food. So the only probiotic in this food is whatever the manufacturer is adding - which we don't know, as they aren't saying. That bothers me. I don't know what, or how much is even being added, so clearly I don't know what I would be feeding to my fish.
Secondly, according to the pic on their facebook page, this food contains wheat, soybean, and rice, and personally I avoid any/all foods that contain soybean meal, ditto to rice and/or corn. Wheat in smaller amounts used as a binding agent I have no issue with, the other two are simply used to lower production costs by the manufacturer, and soybeans are known to contain anti-nutritional matter that can affect the overall health of fish, especially those that are on the carnivorous side of the equation. Most fish only require a small amount of spirulina in their daily feed, 1.5-2.5%, certainly not in the quantity that this manufacturer is adding as the main ingredient. More does not always equate to better.

The study they show for their AEE Gold certainly is a farce, as it doesn't show the nutrient profile of the test commercial feed. It's easy to beat out a low quality feed when none of that data is being released.
Most quality fish foods on the market today contain spirulina, in a more correct balance, taking in the entire overall nutrient profile of the feed, and the fish consuming it. Probiotics are easy (and dirt cheap) for any hobbyist to add to their system.
If as you said in your initial post, you are interested to learn more about probiotics and the health of your fish, you should click on the link I posted previously, and read-read-read.
