Several friends have gotten on the Blackstone craze and they report using it for breakfast, lunch anddinner. So happy they say, "never going back, you need to try it."So I have a Weber Spirit 300 and until that baby breaks and can't be repaired (7 years and still works like a champ), it is my grill, period. What are you going to do? Well. one option is to order one of these cast iron inserts and put it into your Weber in place of one of the sections of standard grates. Ta da, you have a half of your Weber imitating a Blackstone and the other half is still your (my) trusty Weber! Seriously, that is all you need to do and this unit fits like a glove. A real chunk of metal and it's not fading away in any quick hurry. Oil that bad boy up and you are sautéing your veggies while the burgers grill next door. Pretty cool actually and it works well. Gets really hot with the flavorizor bars still in place, don't worry about that.Now, that said, don't think you are going to get all Bennie Hana on this insert, in fact you have to be kind of careful, because you have a limited amount of space to work with. The insert has upright sides, so your items don't just roll away, but it's not that big. If you have to do more than six burgers along with the veg, then you might run out of space. But here's the deal; if you own a compatible grill, you get the chance to see if a flattop is for you. Ultimately, my wife and I had the flavor comparison and agree that for us, the char of the grill is key for the things we cook on it. We tried Smash Burgers on the flattop and there's really no comparison. The grill wins hands down.But its up to you and this is a low cost, low risk way of checking it out for yourself. We will continue to use this insert and grill half and half, on it for fragile foods such as fish and the killer job it does on veggies.
