It's working good. I can recommend the fan.

So I have had this unit for 3 months. Completed around 8 cooks. Most are low slow, past week cook was over 14 hrs.

Pros:
Cost - compared to others this a cost effective alternative to bbq temp control for long slow cooks
Design- love the simplicity and sleek design
Connection - stable WiFi and no major issues I see
Durability- at this point seems ok
Temp accuracy- seems to be good

Cons:
App- it is ok, but it is buggy. It needs to be cleaned up and even allow for more control of unit and temp settings.
Temp control- ok here this is where it needs improvement. The “Open Lid” control doesn’t work at all. Also the unit will over shoot temp every time as fan runs at 100% until it hits temp. They need to adjust this to run based off temperature. Example would be: run at 100% until 75% of target temp the turn fan off. Measure temp for 5 min then start fan based off that temp. I am manually doing this but this would be game changer. Not a programmer but it doesn’t seem difficult. They could even expand the app to allow owner of unit to adjust based on their cooker.
Probes: allow you to upgrade probes. Probes are good with but I want a better looking probe like there other units.

Overall it is worth the purchase. I have owned Guru, Fireboard and others. But this right here is on track to be the best. I hope they invest in the product and don’t just put on back burner. No bun intended.
