I just got my PartyQ last night. I will be doing an overnight low and slow Friday on my Kamado Joe. I will update on how it goes this weekend.
So far the unit looks like nice quality. And I can confirm that the temp probe is now removable, so it can be replaced.
Only thing to do is figure out how to rain proof it. I think the easiest way is to make a rain box and just run a hose from the fan in the box to the adapter on the kamado. It should be pretty easy and straight forward.
