Beast Academy?

Has anyone used Beast Academy math? http://www.beastacademy.com

I’ve read great reviews about it, but I was hoping to get some CMers feedback on it. I’ve looked at samples and am intrigued by the approach it takes to math concepts.

We are using MM and LoF for 2nd grade, and have used RS A and B for K and 1st before starting MM. I was thinking about adding in some BA for the extra challenge or maybe to replace MM when we got to the appropriate level. I’m also pondering Strayer Upton Practical Arithmetics instead of MM after the recent thread. There are so many options for math that seem so good! I just can’t figure out which direction to take. I know I just need to pray about it, but some helpful opinions from the awesome folks on this forum couldn’t hurt! 🙂
