Query: Seller must revise product description...

This is just to be informative. The seller must revise the product description as it states it fits the Q300 when it does not. Only the Weber Q 1437 fits the Q300. I found this out recently after I recieved my order and now have to return it. I rate it 1-star due to sellers incorrect product description.
