  1. Wow, best cooking grate EVER 5 Star Review

    Posted by on Jul 10th 2019

    I have never been able to BBQ meat to perfection before on ANY of the grills I have owed. These grates turned my so-so grill into a 10/10 grill. It cooks so even, no hot spots like before. Makes it much easier to control the cooking process.

  2. Everything that was promised 5 Star Review

    Posted by on Jun 27th 2019

    I bought a new Weber Genesis - a model that came with stainless steel grates. I wasn't sure that I wanted to spend more money on another set of grates, but Amazing Ribs raved so much that I decided to give them a try. I'm glad that I did - really awesome the way that they even out the heat and how quickly the grill heats up using them. I was so impressed that I bought a set for my parents about a week later!

  3. Especially "grate" for hard-to-grill items 5 Star Review

    Posted by on Jun 20th 2019

    These grates are everything I hoped they would be, and more. I love that there's no flareup, which is especially important for those high-fat items like greasy hamburgers, bacon-wrapped poppers, and a decent rib eye. On my Weber Genesis, I'd occasionally grill fish, but with the cast iron grates, only with a basket. Then the basket was tough to clean up. With GrillGrates, grilling fish is no more difficult than grilling, say, hot dogs. I've stepped out and tried a few things I'd never grilled before -- sliced potatoes, sweet potatoes, peaches. All of those would been problematic on the cast iron grates, but a piece of cake on GrillGrates. Someone else mentioned a gap. Yes, there's a gap on my Genesis E-310, but that's fine with me. I keep my grill surface split 60-40, with the gap between the two sections. That just makes it easier to separate it into 2 temperature zones.

  4. Worth every penny 5 Star Review

    Very pleased perfect fit made a Huge difference in my Weber Grill. Worth the money!!!

  5. Weber flare ups solved 5 Star Review

    Posted by on Apr 2nd 2019

    I was constantly fighting flare-ups on my Genesis II E310 because of its poor design. Ordered a set of Grill Grates that fit perfectly. Seasoned with hamburger which did not flare up. Have grillled chicken and steak with no flare-ups. Wish Weber would chunk their grates and go with Grill Grates as standard equipment.

  6. Best grill product - EVER! 5 Star Review

    Posted by on Sep 18th 2018

    I now have Grill Grates as replacements on all of my grills, including a ceramic "egg". These have saved me money on propane and charcoal, as the Grill Grates heat up better and require less source heat. These are hands down the best product on the market for grilling.

  7. Best investment grill owners can make.. 5 Star Review

    Posted by on Jun 14th 2018

    I never write reviews but I need to give credit where due..I am always skeptical with the products I purchase and these grates were no different..I decided to purchase an expensive grill..Its a weber Gen II propane.. 8ve always had issues with gas grills because they all flame up and also have the dreaded cold/hot spots.. With grillgrates, that problem doesn't exists no matter where on the grate u cook it's all even heat they leave perfect sear Mark's and hold the heat as well. Customer service is very helpful shipping is fast, and packaging is also on point..I purchased the replacement grates and they fit as good as the factory grates..I would def advise purchasing the cleaning brush bc it fits perfect in the valleys..Also be sure to remember the surface temp of grates runs hotter than the air in the grill.. That being said I would recommend an infrared surface thermometer..You cant go wrong with this product, I've always believed in the saying "you get what you pay for".I def would spend twice what I did on them..

    Brad here- Kevin you can write copy for our marketing department! Enjoy that new Genesis II it is the latest in a long line of great gassers from Weber! Thanks again for calling out our customer service too- we want people to call thats why our phone # is all over our site! GrillGrate, Eat Well!

    Grill grates are awesome! Before buying I read quite a few reviews on the web, because I had never heard of them and was skeptical. It was clear in almost every review I could find that Grill Grates would enhance my grilling experience - even on a Weber BBQ.
    Now that I've actually used them, I agree they are an excellent addition!
    It takes a few times to adjust your heat and maybe your cooking style a little, but it's easy to figure out.
    I keep (3) of the grates "griddle side up" and (2) of the grates "rail side up" on my new Weber Genesis E-310. The ability to "pan fry" and produce a nice Maillard effect on the griddle side for asparagus, other vegetables, burgers, etc. adds a whole new dimension to what you can do on your grill.
    It was obvious after the first meal that these were great. After cooking several meals I was 100% all in. Remember, you have to heat a little differently and season/clean a little differently at the start, but it soon becomes clear that you shouldn't own a BBQ without Grill Grates.
    Having said that, for some reason it was several weeks before we finally grilled some skin-on chicken breasts on the rail side. OMG - wait until you grill chicken breasts! Tender, juicy, 1000% better than any other grill or oven cooked chicken breasts! No flare ups, and significantly more tender.
    A little pricey in my opinion, but I wouldn't be without them now.

  9. GrillGrates is no doubt one of the best upgrades you can do to your BBQ. 5 Star Review

    Posted by on Apr 2nd 2018

    I purchased GrillGrates for my new Weber Genesis II E-310 grill. The grill came with heavy duty porcelain/cast iron grates; although I wanted to start grilling right away I waited for the GrillGrates to arrive. When I received them they were well packaged and came with the GrateTool which is perfectly designed for flipping and cleaning the channels. The GrillGrates fit perfectly. There are 5 panels in this set and I turned 2 of them over to get a griddle type surface. Next was seasoning them so I checked out the GrillGrates videos on how to do this. After a few cooks the GrillGrates were now blackened and had a non-stick coating. Also on the website was information stating that the GrillGrates run hotter than normal grates upwards of 200-250F, Now I cook at medium to low heat settings which saves fuel. Do yourself a favour and purchase some GrillGrates as you'll be totally satisfied with your decision.

  10. Just Get It 5 Star Review

    Posted by on Mar 13th 2018

    Best thing since sliced bread
    Best thing since indoor plumbing
    Best thing since hot water on tap
    Best thing since_____(well, I think I better stop right there) Get yours. I have three sets including the 18" Weber Smokey Joe, 22" Weber kettle and now my Pit Boss 820FB Deluxe Pellet Grill.
