i.love my Lumin grill. It has the typical Weber build quality, and gets really hot, which is what I was looking for. It fits very nicely on my apartment balcony using a Cuisinart grill cart. My only complaint is that the controller and cord obstruct a large portion of the area on the right side of the cart table. Overall, I'm very pleased with the grill.
This grill does everything it says it can do. While I've only had it about a month, it does burgers, sausages and can simultaneously steam vegetables. I also bought the stand, which is plastic, but it seems very sturdy and the grill fits it nicely. I only wish there was a model one step bigger. I'm able to do 4 burgers and a plateful of steamed veggies (or I could do ~8 burgers) so it works for me 99% of the time. I have not tried the smoker feature.
