Hi Keith,
I’m an educator (instructional technologist specifically, though I was a K12 classroom teacher in a past life), and it helps to have many of us onboard here. Anker’s projectors (so far) aren’t quite up to speed for a well-lit classroom. They’re more personal entertainment devices than teaching tools.
However, I have tested lots of products for Anker - the best way is to participate in the giveaway contests and enter their drawings, etc. It’s tough to be a power user (you need a LARGE following on social media to get to that level). Anyway, start writing reviews. Also, as an english teacher I also always told students to READ a lot to be a better writer - same thing with reviews. Check out these forums and see what others have done and learn from it.
