Extremely high build quality. It's heavy. Solid. Nothing flexes or bends. The temp displayed is very accurate when referenced with a thermometer. My only complaint is that the 2-piece diffuser should either be standard equipment, or an optional upgrade at order time (in exchange with the stock diffuser). The 2-piece diffuser is a MUST HAVE accessory. Cleaning the firepot is a messy pain the A** without the 2-piece diffuser. I didn't think I would need it, But I ended up ordering it about 6 weeks after receiving my YS640. I also highly recommend the direct grilling grates. I was able to get rid of my gas BBQ because the direct grilling feature works so well on the YS640.

Pellet grills come in various sizes from the portable types for tailgating to the extra-large units for commercial use. If you are someone who wants to be able to take your smoker on the go, be it camping, partying or any other event you’ll want something that’s easy to lift and has wheels to facilitate movement. If you have lots of parties and gatherings at home, then you might want something bigger. Its all up to what your needs are.


I have found that using the upper shelf gets more airflow around the meat than the lower shelf. I asked the AmazingRibs.com science advisor Prof. Greg Blonder about the problem (he has a MAK 1 Star). He explained that smoke sticks to cool surfaces and wet surfaces, and the surface of meat warms and dries out after a few hours. When he wants more smoke flavor he uses a strong smoke wood like hickory or mesquite, he starts with cold meat, and then he keeps the meat moist by painting or misting it with apple juice or a mop like Lexington Dip or East Carolina Mop or Texas Mop Sauce. A awter pan can help because the water condenses on the cool meat and attracts smoke. Read his detailed research on the subject in my article on the Science of Wood and my article on Basting.

Recently bought portable Traeger ptk+ smoker as camp a lot. Food is amazing though grill size better suited for 2-4 ppl and you can’t fit a large roast. However cooked a rack of ribs, several chickens and burgers. Food comes out amazing. You do need electricity hookup camping and it drains too much power to run off cars dc socket. $300 and of you call them to order v online they will throw in free weather cover free shipping and some rub. It does take up some room in car so beware if you have tiny vehicle. Buyer beware racoons love smoked food so remove your trash bag with bones from campsite before retiring, as we found out the hard way
The Sense-Mate feature is another one of the best additions to this smoker: it is a thermal sensor system that monitors and reads the internal temperature of the grill within 5ºF of the actual temperature! Once you set your desired temperature using its digital controls, the Sense-Mate technology reads and monitors the temperature, while displaying it on the LCD display. Sense-Mate makes sure that heat is kept at a constant temperature, so whether you are cooking at 150ºF or 550ºF, you can rest assured that your meats will be evenly cooked.

My wife and I were one of the first buyers of the YS640 in 2010. We had owned a couple of gas grills that, of course, eventually rust out. My wife saw the YS640 at the Kansas State Fair and called me and said that I HAD to look at this smoker! At first, the smoker had many problems--inaccurate temps, huge swings in temps, etc. Don and Joe kept working on the problems and installing updates--never charging us for updates or service calls. Finally, in about March of 2011, they installed the update that really was the solution. Since then, the YS640 has been a consistent workhorse that does everything as advertised. Built like a tank. built to last. Don and his staff stuck by his product and by his customers. In this day and age, customer service is uncommon. By the way, I thought the YS480 would have been big enough, but my wife said, "our family isn't getting smaller,".....I'm very glad we got the 640 and the second shelf. I have needed it many times. Thanks Don!
The Smart Smoke technology is one of the most convenient and easy to use features on the grill. It contains a dual LED temperature readout that keeps the heat at a constant temperature. This means you have more time for socializing and can sit back and relax. The temperature ranges from 160 to 500 degrees Fahrenheit. The grill uses a pellet feeder system that burns slowly to add intense flavor to your food. It also uses an electric auto-start ignition that requires the grill be plugged into a standard 120v outlet.
Whenever you want to smoke with a pellet smoker, you will have to make a choice: What type of wood pellets should I use? Well, the answer may sound simple – whichever flavor you like the best – but might be pretty difficult if you’re smoking for the first time. Unfortunately, the only way to know which flavor you like most is to try them all at least once and then decide upon which one floats your boat.

Instead of logs, the pellet smoker is fed with food-grade cylinders of wood pellets that are an inch long and ¼-inch wide and are made of compressed hardwood sawdust. According to the best pellet smoker reviews, pellet grills are easy to use because it’s easier to maintain its temperature because of these sawdust pellets that are subjected to great heat and high pressure, which ignites lignin (natural wood glue).
The wood pellet grill features a dual rack design with a 513 square inch main cooking surface and 187 square inch warming rack. With a 20-pound hopper capacity, the grill has plenty of space for wood pellets to keep grilling during long event and parties when you have many mouths to feed. An automatic pellet feeder makes it easy to maintain the desired temperature, so you can focus on just the grilling itself.
