Customers are mixed about the lighting of the barbecue grill. Some mention that the system works perfectly, lighting each burner immediately each time they use it.

Great Grilling but Some Features are Suprisingly Poorly Designed
4 Stars
Great Grilling but Some Features are Suprisingly Poorly Designed
We are so tired of buying the cheap Charbroil and almost all other BBQs that after 2 years turn into a useless pile of rust, even if they say they are Stainless. So were splurged on our last BBQ that was 2-3 times the cost of those others. We used it once so far and were very happy with the performance, however, the design quality needs improvement and we were very disappointed in some of the cheap design features for such an expensive item. One of the reasons you pay top dollar for the BBQ is the warranty and warranty support. That is top-notch. Read on for our experience.The Bad: -- BROKEN PLASTIC PARTS: On assembly, the cheap plastic tabs holding the stainless front panel that covers the control valves broke off and the panel will need to be replaced. There is no repairing it. -- EASY TO STRIP PLASTIC THREADS: The ignitor assembly 1 of the 2 screws was too short to grab and hold the ignitor to the sidewall and the other one stripped on the first try. The ignitor housing is made of soft plastic and the screws cannot be tightened without stripping the plastic threads. -- LOOSE PARTS INBOX: We found a screw floating loose in the box when unpacking and discovered it belongs to 1 corner of the separate burner. When try to reattach we discovered the hole was stripped at the factory and the screw would not grab. -- POOR TOOL HANGER: There are 3 plastic hooks on each side, sometimes too large to hold tools. Why not make a bar that is more universal and more convenient to allow hanging all the tools, not just 3, and not just the tools that will fit over the hooks. -- NO SHELF STORAGE: The left side shelf is a large hollow unused volume. Why not make this a drawer or have a lid for storage? -- HAVE TO LIGHT EACH BURNER: Each burner has to be individually ignited. Unlike other BBQs where a burner will then reach over and ignite the one next to it, Genesis II will not do this. Each burner has to be ignited with the spark ignitor or a match. -- CONDENSATION IN THERMOMETER: Water builds up on the inside of the thermometer and could potentially obscure the readout and damage the mechanism. This has happened on other BBQs I've had and was surprised to see Weber had not improved this design.The Good: -- FAIRLY EASY ASSEMBLY: Fairly easy to assembly and the phone app with 3D drawings was helpful. It took 2 of us about 1 hour to assemble. -- PROVIDED WITH GAS QUICK DISCONNECT: It's provided with a gas quick disconnect which we didn't realize until I played with it as I was planning to buy one. That is a nice convenience. -- NATURAL GAS IS HOT: We had our backyard plumbed years ago to provide a natural gas outlet and we purchased the NG version of the S-435. We read that NG is not as hot as propane so there was some initial concern there. We found that NG works perfectly. The Genisis II got hot fast and reached close to 700F with all burners on during the initial 20 minutes recommended burn off. -- HEAVY SOLID GRILLS: there are 3 sections of stainless steel grills. There are much bigger and heavy-duty then most other grills and they left a nice BBQ line on the steak I cooked. -- GREAT SUPPORT: We called warranty support on day 1 and quickly got hold of someone. There was no hesitation or issue on their end and they immediately sent our replacement parts for free for the broken gas valve cover and stripped ignitor assembly. Of course, they can't help with the poor/cheap design that caused these problems in the first place but at least we can start again with new parts. -- GREAT GRILLING: Cooking a steak was great. I used the sear feature and cooked a 1-inch steak in about 7 minutes to a perfect medium rare with nice outside color and grill marks. -- LITTLE FLARE UP: When the steak dripped fat, the burner covers diverted it away and I did not have any bit fare ups which was always an issue with other BBQs. When fat dripped there was an initial flare but not sustained flame. -- DOUBLE WALLED DOORS: I like the fact that the front bottom storage area doors are double-walled which gives them a more substantial look and feel and makes them stiffer. I also like the magnet closure that works well.

A ce prix, je crois que le BBQ aurait du venir avec les 2-3 connecteurs les plus fréquents. En ce temps de Covid, trouver cette pièce sans connaissances en ce domaine est difficile et une perte de temps incroyable. Ça fait 1 semaine que le BBQ est monté mais inutilisable. Ceci est inacceptable.
