I have owned my WSM for over 8 years now and have done alot of great cooks using it, It's so easier to maintain low and slow temps of 225-275f and for long periods of time with minimal adjustments to the air flow.
I've only had one issue with my Weber which was probably my own fault which caused one of the cooking plates to start to lose its protective coating and called Weber's costumer service number hoping just to order another to pay for myself but they sent out free of charge and this was after 6 years of use!
I swear by my weber and have since bought a Weber Q and multiple accessories from the brand.

Been using a homemade ugly drum smoker for a while and treated myself to one of these. Glad I did, smoking meat is too easy now and takes up less space in the yard. Also less fiddling with the vents to keep the temperature regulated compared to my old beast.

Purchased the smoker in 2013 and have had excellent performance, not one failed cookout. Some minor shortcomings which have been addressed in later models. In 2017 the assembly closing the door failed. That the smoker was well outside the warranty period Weber Customer Services is providing a new assembly at no cost. We have other Weber products and all have performed well.
