Spire Premium 5 burner drop in gas grill arrived in perfect condition. It was well packaged and was easy to convert to natural gas. Instructions are clearly written and pictures are easy to read. Love the interior lights. This function came in handy while removing the LP orfices. Can’t wait to drop it in, hook to natural gas, and grill. ... show more

Size: 30" Built-in Grill
Great grill, absolutely love it!!! Bought it back in December but didn’t build my outdoor kitchen till June, I’ve been using almost daily. The quality was the first thing that stood out, the size has been perfect for my needs, it looks beautiful and is easy to clean with the removable pans , and this grill cooks extremely even , I don’t have hot spots and it gets very fast and I feel that is because of the thick gauge stainless steel… I’m very impressed and I don’t know how other grills that cost 2 or 3 times more could possibly cook any better… if you are on the fence just buy it you won’t be disappointed ... show more

Size: 30" Built-in Grill
Great product, good quality BUT I nees to do an exchange. Product arrived, no visible outside box damage. When installed. I noticed the lid was off against the corners when closed. Not big deal but still not good for a $900+ grill. The grease traps are also off (not aligning either) creating a gap. I think the "frame" is twisted or not even, creating this "issues". Work on my new kitchen for the holidays and to host family. I had to use it twice, so perform and functionality is perfect. I want to exchange the grill for the same model but making sure the frame is 100% in position. Not option for exchange available, with less than 30 days of buying it. ... show more

  • Good grill but there are some additional mods required for conversion to natural gas
Size: 30" Built-in Grill
The grill is well-made and looks very nice out of the box. The assembly and installation are very straightforward. HOWEVER, this grill **does not** include an insulated grill jacket, so if you are installing this on a new construction home and have to get it CO'd, you will need a separate grill jacket to get it past code. Also, the burners are not "out-of-the-box" ready for natural gas connection. Besides the required gas conversion kit, you will need to change out the gas modulators on each burner; otherwise, your gas flow on natural gas will be extremely limited, and the flame will be significantly restricted. ... show more

  • Magnet does not stick Magnet does not stick
Size: 30" Built-in Grill
For the price, considering others is very well-made.Say 97% stainless that does not stick with a magnet. The only thing I could get to stick was the main grills but that’s really not an issue because you can always get new ones the burners, the shields, the shell, the grease tray all the hardware, except for the pinch bolts a very few, I don’t think are stainless I can’t tell for sure but those can always be replaced but your main grill all seems to be stainless if good quality I bought this because I’m tired of my grills rusting out and I think I will be happy. I have not used it yet, but seems to be of good quality. ... show more
