I just had a great look under the hood of one of these units and I'd agree with fballfan2. I took some pics to show why:
Here's the grill, badge and sales fluff on the grill outside the store:
I moved inside because it was getting windy and dusty and found the same grill in the showroom. I opened the hood on this thing and the first thing I did was look at the grates.
On the surface they look like solid stainless steel grates.
There's even a cute little grate-level thermometer on each grate. But flip the grate over and that's where things get disappointing.
The actual cooking grates aren't solid anything. They're hollow tubular grates and seem a bit flimsy. They may have been stainless steel but they felt like aluminum. Plus, since they're hollow they don't have the thermal mass to conduct heat as well as solid grates. But let's dig even deeper.
Here is the baffle beneath the grate. I was suspicious because I figured it might just be a flame spreader for a standard burner.
That suspicion was confirmed when I saw a basic V-shaped flame tamer....
... and a basic grill burner beneath it.
So call it what they like, this isn't a true infrared grill at all. It's a basic gas grill with a bunch of baffles on it. I also believe that those baffles will also catch grease like crazy and flare up. Also, since the holes are so small I can already tell that the baffles won't spread the heat evenly, especially since that v-shaped flame tamer is beneath it.
By contrast, here is a true infrared sear/side burner on my grill.
This grill uses a ceramic element instead of just a baffle. You can actually see the glow from the burner - that's true infrared cooking. (And that's Steven's grill scraper in the pic - a really nice tool for heavy grill cleaning.)
Finally, I want to thank the staff of the Lowe's store I went to for not bothering me when I took apart his grill - at all. I spent 25 minutes on their sales floor and didn't get approached by a single salesperson even once, although the store was almost empty of customers. (Maybe they all went on an extended coffee break at once?). Though it was nice not to hear "Can I help you?" every 3 minutes, I dread to think what a customer would think if they really wanted to buy a grill - or anything, for that matter.
