Hear From Other Grillers

Genesis SPX-435 Smart Gas Grill (Natural Gas) is rated 4.5 out of 5 by 435.
Rated 4 out of 5 by from Recommendation with smaller downturnes The most important part: the grill brings a lot of “grilling fun” and I like the overall quality which means –overall- a recommendation to buy. But - I also found some downturns from my personal perspective. History: I had a Weber Genesis silver B gas grill for about 20 years and was extremely satisfied although even this grill did cost its price long ago. After 18 years I opened the first time the gas pipes and found ... nothing, no issue at all. All perfect. The only thing I did is to replace the ignition unit one time and the flavor bars two times, which is normal for the time I used it. After moving and not taking our old grill with us I first bought a grill for 399 USD. After one year it stood at the street to be taken by someone else. It did not provide the “grilling fun” at all I was used to before. So this time we bought the SPX-435 Genesis. And I can pretty good compare this new one with the “old” one, i.e. the previous silver B Weber grill. What I like more - The grill space - more than enough for "normal" usage and about 1/3 more than with the old one. - The extended grill space to be folded if not used. Better than the old grill which was too close to the main grilling area and too small. This one you can really use. - The grill griddles to be rearranged – more flexibility. - The 5 burners with the searing zone. This is very effective. - The additional burner on the left side works great for heating sauce or cook something in parallel. - The simple but very effective measure for showing the remaining gas in the gas bottle. More reliably than all other in-pipe measures I had. - The wheels are much better than with the old one. So you can more easily move the grill on halfway flat ground. However they could still be a bit larger - with the old grill I have replaced them with large air filled ones so I was able to move it even along grass to show up with the grill in the front of the garage. Some improvement left! - Building it up is not too complicated and normally should be easy to understand even if you are not building a house every day. Just the pictures could be a bit more brighter especially because almost all pieces shown are dark. Suggestion: hand it over to a Swedish furniture provider and let them rework the pictures and details! - The large preparation space on the right hand side. - The lights in the handle. - Switch on the light of the buttons via the app ….. a nice gag … - The Weber connect app in general. What I do not like that much: - Yes, it has a display for the temperature. However one simple, analog thermometer in the opening lid in addition would not have been bad. Just in case the display is not on or hard to read due to the sun. 10 USD which would be nice if it would be built in. - I could connect it to a normal power outlet. However and because I do not want to have all the cables in the patio (and there is no outlet directly at the grill) I prefer to be independent and use a 5V power bar, which is more than sufficient for the power consumption. But after a while the display seems to switch off and also disconnects from the Wifi net at the same time, which is not convenient. And I have not found whether there is a configuration to influence it. You lose the temperature control on the mobile app and have to switch the display on again manually. - It only uses 2.4 GHz. All other devices in our house use 5 GHz. So I had to turn on the additional WiFi network just for the grill. That would not be needed today. - With my old grill I lit the first burner (with the ignition as today). Once I turned the second on the fire from the first burner automatically lighted also the next one and the same with the third one – pretty easy and very secure. With the new grill I have to ignite again each time a burner is turned on. Not a big problem but not that convenient as before and not as safe! (Or did I do anything wrong?) - I am missing on the website a function to just show all available accessories for this specific grill type. Either I did not find it or Weber does not want to make it easy for me to spend more money? Actually this is an advantage … - I have not found a longer inner fork for my existing motor for the rotisserie because the new grill is broader. Is that available or do I have to buy the whole device? - My old grill had an open space with metal griddles on the bottom instead of the doors. YES, this does not look that ”clean” as a cabinet. BUT if you have a hot but empty griddle (or alike) you want to take from the grill it was very easy to just place it down there and wait until it is cool. I am missing such an easy to reach place with the new grill. Yes, you could use the right preparation zone with some heat protection on it. Fair enough this is a problem not only of this grill if you have doors in front. And it can be solved by e.g. an add-on table. Anyway, the old one was easier to handle. - It looks to me that my mobile phone connects to the grill only via Bluetooth although the grill itself is connected to the WiFi net. So I cannot leave the grill too far behind although my WiFi would be available in and around the whole house – not the Bluetooth of my grill however. Or did I not find the correct configuration? And if so we see that the description or help regarding the configuration is not sufficient. - To the left and the right of the extended grill griddle the sides should be a little bit higher and not almost even with it. Why? If you have a pan or similar on it and want to re-order the content a bit it is very likely that you will move the pan sideward and over the borders at the side so you get in trouble to not move them too far and get them back. Sides ½ inch higher and it would be good. - Finally I bought the rotisserie set 7653. o Biggest issue: the fork is so long that, even if you take off the extensions you cannot open the lid of the side burner during it is in use. Whose concept is this? Please shorten it and send me a new fork once conceptually solved differently. Thanks! o The cable leaves the motor towards the front. Why not the back? In the front we have the preparation area. Not meaningful to have a cable here. o The grill should provide some dedicated space to especially store the fork. o Inserting the fork into the motor lifts the latter by ½ inch. It still has enough grip inside of the holder but why not having the holes for the screws a bit higher? Overall: a grill I can recommend, but some details could have been made a bit better – with only a few thoughts.

Rated 5 out of 5 by from I would buy it again The Genesis SPX-435 with Wifi is a great grill. I have been using it now for about 7 months and feel like the performance is as advertised. The grill being natural gas is super convenient to use, just hit the self light buttons and get started. The app has great features to make sure you are not over / undercooking the food along with creative recipes. The construction of the grill is solid with thoughtful features and plenty of add-ons. I highly recommend this grill and would buy it again myself.
