Purchased the YS640 about a month ago. So far I have cooked nine pork butts, three racks pork back ribs, one beef brisket and four thick cut New York steaks on it. I am very pleased with the results of these cooks. I have an upright propane smoker, Weber kettle, propane grill and so far the YS640 has out performed all three of those in ease of use and flavor performance. I can get almost the same flavors with my others, but takes more work and babysitting. Also want to mention that the YS640 is built to last. I noticed the ruggedness and excellent USA craftsmanship immediately upon arrival. Some reviewers think maybe the YS has a steep price, but I think its justified due to its construction and craftsmanship. It would be difficult to make something of this caliber for any less. A couple minor things to note is you will have to play with the damper a bit to learn the heat distribution, but after learning it, its not a problem. Doesn't put quite as strong as a wood flavor on the food as my upright propane smoker, but it puts the right amount and I have no complaint here. I would and have already recommended the YS640 to friends and acquaintances. If you have spent long hours smoking foods and know the correct flavors that they should be, your not going to be disappointed with this cooker!
I am a pellet grill newby and a recent convert from the backyard charcoal grill to the Yoder YS640. After a ton of research on pellet grills, I jumped in the deep end with this grill and have won raving Family fans after four grilling adventures. I have never cook ribs...tried three racks using a special rub and several ours on the Yoder...and my wife who isn't fond of ribs was eating the left overs the next day! This grill is easy to use and creates fantastic tasting food. My only regret is that I didn't purchase the grill a lot sooner.
Although these are marketed as grills, they do much more, including baking or roasting. Because they heat by convection, you might not get the grill marks that a gas or charcoal grill will give you, but you also won’t have the flame-up problems. While many pellet grills offer high cooking temperatures, the maximum depends on ambient temperature and wind. Many users wrap their grills in special insulating covers to help maintain heat, reduce fuel use, and reach the higher temperatures they desire.
