Yoder Smokers Community Forum

I'm wondering if anyone has used a TipTopTemp temperature regulator on their 'S' series Yoder pellet smoker and has thoughts on them? I happened across them doing some research online in preparation of my Yoder arriving next week and it seemed like an interesting little device considering I've read a number of complaints/comments on the forum about larger than expected temperature swings. I can also see how it might not contribute anything or even be inadvisable with the built in fans and ACS. Lemme know if you've tried!
