I'm,not gonna set again till I get the 9300 circulated air,or even newer model.In you'll a eyes what bator would be the best to get.
Honestly I have a 9300 and I pitched the heating element and purchase the incukit with a fan for 40 bucks and swapped them out. Much more stable and I also use a separate therm/hydro combo just to make sure the therm is accurate on the incukit.
