very good

It has a minor issue with the battery indicator, which shows varying voltage readings right after the battery is inserted, but it works correctly.

Love it

So far it has worked well for such. Cheap board it amazes me how well it has run I was looking for a affordable option and this was really well built so far so good!

These work great, when they work.

I bought 15 stacks and used 14 of them. I had two that failed for different reasons. I hope these issues get resolved because this is a fantastic price point for teaching drone education.
