Hear From Other Grillers

GENESIS SPX-435 Smart Gas Grill (Natural Gas) is rated 4.5 out of 5 by 351.
Rated 5 out of 5 by from No regret purchase. Adapter needed for natural gas What you would expect from the top-of-the-line grill. I got the natural gas version and some elements of this review are specific to this version. I had the reseller put this thing together. $100 well-spent. Not because I couldn't do it but because I didn't have the 2 hours it took them with two people. It probably would take one person longer. Also, retail assembly will not connect the Weber gas line for liability purposes even if they assemble the grill. The LED lights are a nice touch. The LED lights are AA battery operated. However, you will need AC power close to your grill for use of the temperature monitor. Remember to remove the plastic protective film from everything prior to assembly and prior to firing it up. Otherwise, you risk baking it to outside of the grill. There is plastic film that ends up between pieces that you approximate together so you need to remove the film before assembly or you won't be able to get it all off afterwards. My biggest complaint is the natural gas connection. Most new construction homes have a natural gas pipe that terminates in a natural gas 3/4" male end. Why then does Weber (and other manufacturers) continue to use a 1/2" female natural gas end? Most will absolutely need to buy an adapter (which is not mentioned anywhere by Weber). I recommend a single-piece, brass pipe fitting. Search for a "Reducing Hex Nipple, 3/4" Male Pipe x 1/2" Male Pipe." Anderson Metals makes exactly what you need in a one-piece brass fitting (56123-1208). I would recommend this over multiple reducers / adapters / or short lengths of pipe you will need to get at the big-box retailers. The more gas connections, the higher the chances of leaks (and remember to use a lot of dish-soapy water over all gas connections to check for leaks first). It took a while to find this adapter and it delayed my use of the grill by a few days because I didn't realize it was needed it until I went to connect the gas line. Weber: Here is an opportunity for improvement. At least mention this in your manual or better yet, offer this adapter on your website or a link to it or something.

Rated 1 out of 5 by from Not as heavy duty as I thought. This was a great grill until a storm blew threw my neighborhood. High winds caused it to fall on the front and bend all of the control dials. It's currently unoperable.

Rated 5 out of 5 by from Weber is a proven grill and very well made My first Weber gas grill was 25 years old and we decided that we needed a bigger grill space to cook on due to our growing family. We purchased this SPX 435 grill to be used with natural gas. We are keeping our 1st weber as a back up for extra cooking space if needed...it still works just fine. Our new grill has plenty of space to cook for the entire family without have to load it more than once...The grill cooks very evenly and it can hold temperatures very well. We also bought the full griddle and it works great. I researched about every grill available and always came back to the Weber...We use it quite often...Weber is a great brand
