I did. I ran into some serious frustration. It seemed to cook well (obviously, there is a learning curve) but see below for an email I sent the manufacturer about some very serious issues I ran into. Haven't heard back yet.
I wanted to let you know how utterly displeased I am with my grill purchase. Cosmetic damage as well has hazardous results upon igniting for the first time have made me want to make you aware of my experience.
I was leaning toward Weber but the positive reviews I read on various forums (on which I may leave my own feedback based on your response) and price difference ultimately led me to purchase your 4-burner DGA480BSP model from Amazon.
It arrived double boxed with no damage to either the shipping box nor the original packaging inside.
However - once I began assembling I found several areas with very obvious cosmetic damage (photos attached of a couple). When I went to attach the oven to the base I noticed the control panel seemed to be off kilter. I didn't think much of it... just another cosmetic disappointment.
I covered the grill and didn't light it until the following day (yesterday).
When ignited, 9" flames shot out from behind the control panel nearly burning my arm. Had I been leaned over the grill or on my knees I'd be missing eyebrows right now.
Fortunately, I'm relatively handy and I was able to take the control assembly apart and reattach everything properly so that my $30 steak dinner wasn't an additional loss.
Based on the fact the packaging was intact and there was such obvious cosmetic damage, I'm guess it fell off the assembly line and was just packed up without further QC or was a very poor refurbish job (I did not purchase refurbished).
If returning it wouldn't be such a hassle, I'd ship it back and buy a Weber.
I really wanted to love this grill and tell my Weber friends they wasted $400, but it's not looking promising.
