The smoker was easy to assemble, very well built. My only issue was installing the wheels, the threads were painted over making it difficult to tighten the nuts, one of the studs actually broke off but I was able to fix it. Operation wise it has been good, the temperature probes are garbage, both read very different temps so I rely on my own manual probe. The app works but I don’t rely on it 100% because it tends to glitch out half the time. The auger definitely doesn’t like larger pellets so get the smallest ones available. Other than those few small things it’s been very reliable.
