Once you get used to creating things, it's pretty good.
But I find that it's still buggy. I'd give this just under a 4 star, like 3.9 stars or something.
It seems like the developers are actively updating it, I hope the bugs get ironed out. I don't understand why almost everyone has given it 5 stars, maybe fake reviews? This is a real review.
It does the job for our small business internal training, but if I was selling courses with this thing, I don't know... backing up all my course data just in case.
