Z Grills 450A2 Review: Two Years of Weekend Smoking on a Pellet Grill

I bought my Z Grills ZPG-450A2 pellet grill about two years ago, and it has done something my old propane grill never managed: it made me look forward to Monday leftovers. Before this, I was a kettle guy. I still am, for steaks and burgers. But for low and slow, I was tired of chasing temperatures on a rusted big-box propane grill that finally went to the curb. The Z Grills changed my Sunday routine. It has a 459 square inch cook area, a PID V3.0 controller that handles the temperature, a foldable shelf and a side shelf, and it came with a meat probe and a rain cover in the box. I set the temp, close the lid, and go inside. That sentence is the whole review, if you are the kind of cook who wants results on a Sunday instead of a project.

Two years in, I can tell you what the listing does not say. It does not say how good it feels to put a pork shoulder on at 9 in the morning and not think about it until the MEATER Plus tells me the meat is ready. It does not say how many Sunday cookouts with the kids and grandkids it has carried. And it does not say that the cleanup is mostly a grease bucket and a bristle-free brush. This review is the stuff I wish someone had told me before I bought it.

How I've Used It

I am a retired HVAC technician, so I tend to judge a grill the way I judged a furnace: does it hold the set point, and does it keep doing it for hours? The Z Grills has spent two years on my covered concrete patio, and it has held 225 for pork shoulders, 250 for brisket, and 350 for chicken. When I say held, I mean the LCD shows a number and the number stays put. That is the whole job. A grill that holds a number all afternoon is worth more to me than a dozen features I would use twice.

My typical Sunday starts with me putting a pork shoulder on around 9. I use the included meat probe for the first few hours, then switch to my MEATER Plus so I can watch the meat from the kitchen. The grill does not care which thermometer I use. It just sits there burning pellets and holding temp. The first Sunday in May, I put a 9-pound shoulder on at 8:40, ran to the hardware store for a bag of pellets, and when I got back an hour later the LCD still read 225. I did not touch it again until the MEATER Plus said the meat was at 203, which was right around 4 in the afternoon. By early afternoon the kids and grandkids show up, and by 5 the shoulder comes off into a cooler to rest. That has been the routine for two years.

I also use the shelves more than I expected. The foldable shelf and side shelf give me a place for a cutting board and a sauce pan, which matters on a patio with one small prep table. The grease bucket catches the drips, and the included rain cover keeps the weather off it when it sits between cooks. Cleanup is a bristle-free GRILLART brush on the grates and a quick check of the bucket.

What the PID V3.0 Controller Actually Does

The headline feature is the PID V3.0 controller, and for once the marketing is not lying. A PID controller is a feedback loop. It watches the temperature, adjusts the fuel and airflow, and keeps the cook chamber close to the set point. I spent thirty years working on furnaces that did the same thing with a different fuel. The Z Grills version does it with wood pellets.

The practical difference is that I do not babysit it. On my Weber kettle, a long cook means adding charcoal, adjusting the vents, and hoping. With the Z Grills, I set the temperature on the large LCD screen and let the controller do the work. The first time I used it, I kept opening the lid to check, which is the one thing you should not do. Every time I opened it, the temp dropped and the controller had to catch back up. That first cook, a rack of ribs, took an extra hour because I could not leave the lid alone. Once I stopped fussing, it held 225 like a thermostat. The same controller has held 250 for ribs and 350 for chicken, and it recovers quickly after I open the lid to check the meat. When I wrap a brisket, the number drops maybe 15 degrees and climbs back within a few minutes. That recovery time is what separates a real PID controller from an on-off switch.

It comes with one meat probe, and the LCD shows the cook chamber temp and the meat temp. That is enough for a single pork shoulder. When I cook two things at once, I add my MEATER Plus for the second cut. There is no app and no Wi-Fi here, which I actually consider a feature. You walk outside and read the screen. That is the whole monitoring system, and it works.

Two Years of Cooking on 459 Square Inches

The cook area is 459 square inches, which sounds like a spec sheet number until you put a brisket and a pan of beans on it. For our family, four adults and a few grandkids, it is plenty. Last July, for my daughter's birthday, I fit a 14-pound brisket on the left side and a cast iron pan of mac and cheese on the right, and both came off at the same time with the mac and cheese carrying a good smoky flavor. The brisket sat flat on the grate without hanging over the edges, and the pan fit beside it with a couple of inches to spare. I have also done two pork shoulders at once and a dozen burgers for a cookout. For a family that cooks for a crowd a few times a month, that space has never been the problem.

It is sold as an 8-in-1 grill, and I mostly use two of those modes: low and slow smoking and direct grilling. The smoker side is what it does best. The grill side works fine for burgers and chicken, though I still reach for the Weber kettle when I want a hot, direct charcoal sear. Different tools for different jobs.

The temp range is what matters for barbecue. I run pork shoulders at 225, ribs at 250, and chicken at 350. The controller holds each one without me standing over it. The meat probe tells me when the inside is where I want it, and the MEATER Plus gives me a second opinion. One Saturday I ran a shoulder at 225 for 14 hours straight, and the grill never ran out of pellets and the LCD never moved more than a few degrees. After two years, the only change I have made is learning to trust the controller and leave the lid closed.

Build Quality and What Two Years Did to It

The body is alloy steel with a high-temperature powder coating. At 84 pounds, it is a solid, freestanding piece of equipment. The dimensions are 28 inches deep, 45 inches wide, and 49 inches tall, and it has not moved from my patio since I assembled it. Assembly took me about an hour on a Saturday morning, and the included gloves saved my hands from the sharp edges on the shipping brackets. Everything lined up the way it should, and the bolts were already in the right holes. The instructions were clear enough that I did not need help, which is my usual test for anything that comes in a box.

Two years of Kansas City weather, and the finish still looks good. I keep the included rain cover on it when it is not cooking, and the powder coating has not rusted or flaked. The foldable shelf and side shelf still fold and lock. The grease bucket still catches what the grates let through. The LCD screen is still readable in direct sun, which matters on a bright patio.

The honest part: I am careful with it. I do not leave the cover off in a storm, and I empty the grease bucket before every long cook. Last fall a straight-line wind storm blew the cover off overnight, and the grill sat through a hard rain before I noticed it the next morning. I dried the body with a towel and fired it up that same afternoon. It started on the first try, and the powder coating did its job; there is still no rust on the body. A grill is like a furnace. If you treat it like a tool and give it basic maintenance, it keeps working. After two years, mine still starts up and holds temp on the first try.

Cleanup and Maintenance

Cleanup is where a pellet grill either wins or loses me, because I am the one who scrubs the grates. The Z Grills is on the easy side. The grease bucket catches most of the mess, and the grates get a pass with a bristle-free GRILLART brush while they are still warm. I do not use a wire brush anymore after reading about bristles coming loose and ending up in food.

The rain cover goes back on after every cook. The grease bucket gets checked before every cook and emptied when it is anywhere near half full. A few times a year I do a deeper cleaning when the grill is cold, scraping the interior and wiping down the shelves. That is it. No special tools, no disassembly, no drama.

The one thing I have learned: do not deep clean right before a cook. The grill cooks better when it has a little seasoning, like a cast iron pan. I clean the grates, empty the bucket, and leave the rest alone until the weather turns.

Tradeoffs and What I Would Change

No grill is perfect, and this one has honest limitations. There is no app and no Wi-Fi. If you want to check the cook from your phone, this grill will not do that. You walk outside and read the LCD. For me that is fine. For some people it is a dealbreaker. Know that about yourself before you buy, and you will not be disappointed.

It is heavy. At 84 pounds, I do not move it around. It lives on the patio and stays there. If you need a grill you can take to the lake house, this is not it. The included meat probe reads one spot, so when I cook two cuts I use my MEATER Plus for the second one. And the grease bucket needs regular attention, which is just part of cooking a lot of fatty meat.

I also considered the Traeger Pro 575 before I bought this, and I go back and forth on the details in my side-by-side comparison. The short version: the Traeger is a well-built grill, and the Z Grills gives you a lot of the same experience for a different budget. If you are new to pellet grills, my piece on why a pellet grill beats charcoal for beginners covers the basics of what to expect.

Two years in, it still holds 225 like a thermostat, and that is the whole job of a smoker.

Who This Is For

If you are the person who wants real smoked flavor on a Sunday without spending the whole day tending a fire, this grill is for you. It is for the backyard cook who is tired of the propane grill and wants to graduate from burgers and dogs to pork shoulders and brisket. It is for the person who values a cook area big enough for a family gathering, a controller that holds a set point, and cleanup that does not eat the evening. If that sounds like you, the Z Grills ZPG-450A2 is a sensible place to start, and the included rain cover and meat probe mean you are not buying a list of extras on day one.

Who Should Skip It

Skip it if you love the ritual of charcoal and wood, because a pellet grill is a different experience and this one will not give you the tending-a-fire hobby. Skip it if you need to check the cook from your phone, because there is no app and no Wi-Fi. Skip it if you need something portable, because at 84 pounds this grill stays on the patio. And if you regularly cook for a huge crowd, the 459 square inch cook area may feel tight. None of that makes it a bad grill. It just means it is not the right grill for every cook. The Z Grills does one job very well, and it does that job every single weekend.
