Very versatile cooking machine. I had an issue because I had an older-version of the grill. The hopper assembly gasket allowed water to wet the pellets. When the grill started with wet-swollen pellets broke the internal shear pin.
I contacted Weber who sent new parts. I'm an engineer who fixes stuff all the time. I was holding my breath when I opened the replacement part box box hoping I wouldn't have to replace one bad part with another.
The replacement part was a solidly-welded assembly which completely eliminated the gasket that failed in the earlier version. There is no way water will wet the pellets in the fixed version.
My point... Weber really fixed the problem. The support team was as prompt getting me new parts. They were polite and professional when I asked questions.
As a matter of fact - I'm writing this in a thunderstorm which would have me scrambling to cover the original grill. Now I'm sitting at my desk typing...
I'm confident the fix will keep the pellets dry.
There is no such thing as a perfect product but are good products with great support.
Read reviews that people were having trouble with their cover fitting with the accessory tables! I had no problems the cover is well made and looks great! But make sure you use all the straps to secure the cover because high winds will blow it off!
