  1. Weber Silver B - Back in Action 5 Star Review

    Posted by on Aug 2nd 2018

    I had moved away from using the propane grill almost all together. I have the GOSM Smoker and Vision Kamado and life was good. I put GrillGrates on the Kamado and was very pleased with the results, but I didn't have enough room when company was over. So I ordered a set of replacement grates fore the 20 year old Weber. Gave the inside a good scrape and vacuum, and the GrillGrates fit perfect. I have always had a hot spot in the back right corner. The 3 burners run left to right. I tried closing off the built in gap on the right and moved it all to the left. Wow, awesome results. The entire surface is within 15 degrees measuring with infrared thermometer. Cool thing is if I put the full gap on the right side I can get 125 degree difference (dual zone). I now use the propane a few time a week for hot dogs, veggies, and quick meals. The first ribeyes were perfect. I couldn't be happier.

  2. Awesome Product 5 Star Review

    Posted by on Jul 23rd 2018

    Received these a few weeks ago, I have been able to use them a few times. After the first use I thought it was one of the better burgers I have ever tasted. Each time I use the grill, the food turns out better than the time before

  3. Grilling Changed for the Best 5 Star Review

    Posted by on Jul 23rd 2018

    My father-in-law received a Grill Grate for Father's Day. We grilled some chicken and I had to get one. Ours is well-seasoned already because we grill a few times a day some days and it is the best grilling we have ever experienced. So glad we made the purchase.

  4. You won't regret buying it 5 Star Review

    Posted by on Jul 16th 2018

    I have used these replacement grates twice cooking chicken hindquarters and in the past, I've always had to keep and eye on it when there would be flare ups especially when I flipped it over, skin side down which always flares up! NO flare ups with these grates! You won't be disappointed. Well worth the money.

  5. Improves any gas grill 5 Star Review

    Posted by on Jun 5th 2018

    I use the flat side as an outdoor griddle almost exclusively. It puts such a nice browning on meat (grill marks are just psychological tricks, you want it all brown, mmmmm). The cooking temperatures of the griddle side are so consistent on the Spirit 300 series measured with an IR thermometer (LLL=350, MMM=450, HHH=550). It's not quite as greasy as a normal griddle as the holes allow some excess fat to drip away, but you don't need to use much fat anyway because after a few uses the griddle becomes really slick (like if you're not careful when flipping, the food will slide across the surface like a hockey puck on ice). I use fin side up for holding wood pellets for indirect heat, but food doesn't touch that side of the grates (I use a stainless cooling rack suspended between 2 panels of GrillGrates on the sides of the fire box so plenty of hot air can circulate in the dome - leaving all/most of the grates in place blocks a lot of the heat from reaching the dome). These really improve gas grills, I can't recommend them enough. I honestly wouldn't bother with GrillGrates for most charcoal grill applications with the exception of wanting to cook really fatty stuff right over the coals and wanting GrillGrates to block the grease fires (hot charcoal can do plenty of browning through a stainless wire grill if you move the meat around a bit but GrillGrates could save fatty burgers or chicken from flame-ups).

  6. Why didn't I know sooner 5 Star Review

    Posted by on May 28th 2018

    Why didn't I know about these sooner. I recently rebuilt my 15 year old Weber Genesis B and added the Grill Grates. After probably 10 uses I am hooked. EVERYTHING I cook now tastes better than before. No flare ups. Even cooking area. There is not one single negative and I highly recommend them to everyone I talk to.

  7. great quality 5 Star Review

    Posted by on May 19th 2018

    We bought the grill grates to replace the grates that came with our Webex 320 grill. The grill grates fit perfectly (there is a 1-2" space on the side, and that's fine, we wouldn't put anything to grill right against the side anyway). We were a little skeptical about replacing the Webex grates - afterall, they are pretty good to start with. But I have to say, the grill grates are far superior - first, it catches all liquid and fats from going down, second, it's much easier to clean, and third, the double side (flat/ ridges) is perfect for any type of grilling. The quality of the grill grates is very very good, we are very happy with our purchase.

  8. TOP NOTCH 5 Star Review

    Posted by on Apr 4th 2018

    Used for the first time and love these grates. Perfect grill marks and perfect steaks.

  9. Top of The Mark 5 Star Review

    Posted by on Feb 23rd 2018

    Just tried it last night with a marinated flat-iron steak. Wonderful grill marks. Cooked much better than the original grates. Sparked new life into my Weber Genesis. I will have to check into grill replacement for my Trager.

  10. Why did I wait 5 Star Review

    Posted by on Feb 19th 2018

    I had looked at Grill Grates for a previous gas grill which I disliked due to temperature control issues and flareups. I didn't want to spend the money on that grill. What a mistake I made then. These grills have been a huge change for my new Weber. They allow me to grill with lower heat and I can safely leave chicken with skin, grilling and leave to prepare the rest of the meal. The grill marks are terrific too. Don't procrastinate any longer and do yourself a favor. Your family and friends will appreciate it.
