The ZPG 550B2 is the one here with the controller most worth paying attention to. A PID controller measures temperature and adjusts both pellet feed and airflow in real time, which holds a set point tighter than the simple timed feed cycles used on cheaper pellet cookers.
Z Grills also builds in a hopper clean-out and a pellet view window, which sound minor but matter in ownership. You can empty the hopper to swap flavors or drain damp pellets, and you can check pellet levels before a long cook. Its 8-in-1 versatility claim covers smoking, grilling, roasting and baking, though a pellet cooker will not match a charcoal grill's sear.
In year three, the igniter and the fan are the parts to expect to replace. Keep the cover on, empty the grease tray, and vacuum the ash from the fire pot every couple of cooks. It is the value pick when you want better temperature control than the Pit Boss 500 FB2 offers but are not looking for WiFi. Its biggest practical advantage over a timed-feed cooker is how it behaves on a cold, gusty evening, when the controller can open the airflow instead of letting the fire sag.
What works
- PID controller adjusts feed and airflow together
- Hopper clean-out makes pellet swaps simple
- View window lets you check levels mid-cook
- Real-time LED temperature readout
Watch out for
- Not a sear machine like a charcoal grill
- Igniter and fan are wear parts over time
