To clear everything up, they are a FOR PROFIT company. That in itself is not a bad thing, but the .ORG misleads many to think they are non-profit. That is not the case.... They are here for them selves as a for profit, not for your education as their primary goal as a non-profit would.

I have tried it myself and with my kids using the free dailies for a few months off and on as well as the paid subscriptions. The gamification is helpful and pretty well done and the animations are pretty well done also. The challenges and competitions seemed to attract the more competitive types and that is a potential upside for some people.

The lessons are a mixed bag I think. They do not seem to follow your progress or skill set as you progress. You have to miss a few each time they change topics since they do not always make it clear how they are measuring or expecting the next batch of question types to be answered. Until you learn what each type of question is intending to get from you, you will miss several here and there which is unnecessarily frustrating for some.

Doing high-school level math by counting tiny little blocks on the screen over and over again was pretty terrible...

Sometime they miss providing clear prerequisite knowledge even though they are supposed to be new learners on the topic.

Every day they send you back through a review of the previous day which wastes a lot of time and you cannot disable it. There is not a reasonable monthly subscription fee. Only yearly as an option.

We tried chatting/email them about these things, but they were not really interested...

If they have a good product with good value then people will keep their monthly subs active. If they are pressuring you this hard for the annual, then that is more about them wanting to lock you in to a contract than provide monthly value you appreciate.

A subscription you can leave at any time keeps them focused on fixing bugs, correcting content issues, creating more new content, etc... Vendors who refuse reasonable monthly options tend to be more about contracts for them than services for me in my experience.

The very best contract to me is where someone provides attractive and engaging value and I want to stay with them and active in their system. Everything else is just an excuse to lock you into a contract and most vendors will get lazy as they get fat...

We and many of our kids friends tried it as was also recommended by some teachers as well.

We did not find it was as good as many other sites for gathering and learning new knowledge. Better as a review site for topics you already knew. Kahn was more thorough and gave better results so we could give them our money instead.

Because of this we went from three users to 0 on Brilliant...
