1. Stainless steel cooking grates are hard to clean.
2. The grease management system is flawed. When you pull it out to clean it the collection tray is intergrated into the top storage shelf so you can’t easily scrape the grease into the tray.
This is a great grill and worth the money. Every bit is high quality, and it heats and cooks evenly. My only complaint is that it uses a lot of gas due to the number of burners.
I replaced my 23-year old Weber Genesis Silver B with the Genesis II S-435. What a beast this grill is. A lot of space and even grilling. Four burners, plus a searing area, gives plenty of flexibility for direct and indirect grilling.
I needed to replace the webber gas grill I bought 20 years ago so I ordered this one and I'm glad I did. It came fully assembled so I can't speak as to how difficult or easy it might be to put together. The overall quality appears excellent and everything on the grill (doors, control knobs, etc) function very well. The grill has a very large cooking surface that makes grilling large amounts of food very easy. It maintains cooking heat very well and the "charring station" on the grill works really well providing a location where you efficiently put char marks on the outside of your food. I like that the gas tank hangs/attaches to the grill from underneath the right side of the grill as this keeps the tank out of the way and shields it from the elements. My only complaints, if you can call it that, is that along with the grill I purchased the Weber grill cover designed for this grill and while it fits perfectly it is just a few inches to short to fully cover the very bottom and wheels of the grill. It leaves a couple of inches on bottom exposed. No real big deal I guess but it would've been nice if it completely covered the bottom of the grill. I've prepared many meals on the grill since getting it and I'm extremely happy with it. I would recommend it to anyone who loves to grill.
