Are they good or bad never had one before? And I've read mixed reviews

Pretty harmless... they eat coralline algae

see what others think...

 

[Mike Johnson]

Some Asterina Stars are algae eaters, some are Coralline Algae eaters. Some may nibble on a coral. There are many different kinds. The all white ones are known to be harmless algae eaters. They reproduce like rabbits on steroids, so they can become very numerous. I've had a lot at different times and they've never been a problem.

The fact that nobody seems to be able to distinguish the bad ones from the good ones is reason enough for me to remove them all on site.
