The lid is approximately 12” in diameter. It fits both the gen 2 (Robobrew) and the gen 3 (BrewZilla) 35L kettle. I shattered my lid and this replacement fits perfectly.

My replacement had no knobs when received

You have to buy the knobs. The replacement lid did not provide that. They’re not expensive but it is my opinion that the website should state that for convenience.

It does not come with knobs or a handle.

You will have to purchase the knobs separately.

Knobs need to be ordered separately or reused from a broken lid.

It came with the knobs.

I purchased them seperately

No it does not come with handles for some reason.

It came with knobs.

Only the glass lid! No handles

Unfortunately you have to purchase them separately for an outrageous price for what the knobs are and how designed price gouging in effect here and the knobs are really small and barely allow for adequate pick-up of a scalding hot glass lid when used.
