Tunze power head exposed magnets?

Just thought I'd share this. After looking at a fellow members new tunze nano stream wave pump, I noticed the magnets were completely exposed. I decided to do some reading and this was the first thing I found. Worth a read and gives a good explanation of how they are reef safe.
