Someone else mentioned the Tello way before my first post in this thread, but couldn't find the other post to quote it.I mentioned the Tello immediately above your post, so I replied. They are both sub 250g exempt from pilot registration, but one runs circles around the other!
The thing is, if several people in a class about drones at a computer club are hesitant about buying one themselves, it would be tough to convince them to spend $400 when they can spend $80 on a reasonably stable and crash durable quad.
The MM may kill the spark though. That's a closer comparison in price and function.
