Customer Stories

Rated 4.95 across 7,500+ verified reviews.

I'm a backyard smoker who is grateful for companies like DDR BBQ Supply who cares about the customer and goes out their way to make hard to find custom smoker parts and other grilling supplies, then follows up after the sale to make sure I'm satisfied. You can't ask for more than that.

Robert Henson

This is the best thing going. I have an offset smoker and it works amazingly well, saves on charcoal and wood, Keeps the smoker at a set temperature even overnight. Well worth the money I would recommend to anyone.

Richard Williams

It took some time to get the smoker, but DDR stayed in touch with me letting me know the status. Received last week, fired it up over the weekend smoked some pork butts and ribs. With the bbq guru this thing did not fluctuate at all held steady all day long. The outside of the smoker was cool to the touch except around the charcoal chamber, but that still would not hurt you if you touched it. Great if you are worried about kids being around it. Love it so far.

James Booterbaugh

I’m glad I stumbled across this company. Fantastic customer service. Fast shipping, at a very reasonable price. Very pleased with my custom order and the whole process. Great company.

Johnny O’Brien

This is a solid product from a great American company super great communication fast shipping love it. I hope to buy something from you in the future.

Jason Brown

Purchased this product for my husband to replace the original grill grate that had burned through. This grill grate from DDR BBQ Supply was a perfect fit (after speaking on the phone with their customer service to insure the exact measurements) and made from much thicker material than the original product. Would not hesitate to order from DDR BBQ Supply again.

With over 35 years of smoking experience, we started DDR BBQ Supply with a simple goal: to help others cook better barbecue. We've spent decades learning what works and what doesn't, and we apply that knowledge to every product we carry. From high-performance grills and smokers to carefully selected rubs, sauces, and tools, everything we offer is something we believe in and use ourselves. We don’t believe in cutting corners or selling gear we wouldn’t rely on during our own backyard cooks and when we compete in BBQ competitions.
