obviously this product did exactly what it was intended to do. However, It did not self feed, once the compressed chips come out of the bag and into the hopper, the humidity expands them and they get lodged at the top of the hopper. So you have to check every hour and probe it, notwithstanding, the hopper could have been bigger to begin with. 

i.e, you need to watch it. So it goes on the electric smoker, which didn't do low-temp smoke and WiFi. Altogether, the fact that you have to buy another product to smoke low temp and watch it, defeats the purpose.
