Rated 1 out of 5 by from Weber has gone downhill - issue with Summit knobs I bought a new Summit S-670 to replace the similar 6 burner Weber Summit I had for more than ten years. It was great and I never had a single issue with it. I only replaced it because my wife wanted a new one. I just used the new one for the first time this year and the knob has broken in the same way other people have described here. I am really annoyed that I spent $3,349 to get something which is not as good as my old one.

Rated 1 out of 5 by from Broken knobs really!?? I had an older Weber Summit 660. Loved it! It finally gave out so I bought a new. Now a year later half the knobs have broken. The cost of replacements are exorbitant and out of stock. Wow has Weber gone down hill. I sure wished I’d read reviews to see that lots of folks have the same issue before I spent $ 3500 on a plastic BBQ

Rated 1 out of 5 by from Weber has completely gone down the tubes! Went through customer service to get new knobs over the winter. They sent wrong part, now won't exchange them for the right one because it's one month return policy. This customer service for Summit grill owners is appalling. Weber used to be so good to their customers for customer service. It's obvious this company won't be around for long with support like this.
