Don't get Visitherms, won brothers, stealth, glass or titaniums! One stuck on "on" boiling my fish, another ended up with a pin hole that leaked what ever in to my reef killing 90% of my fish, and the third simply exploded electrocuting my anemones, fish, and shocking me.
The last two were on controllers.
I am now running Ebo Jaegers. Not long enough to say anything about them.
