I was aware of this issue via my previous research about the company that makes these Auplex. I am sorry i did not mention it in advance. The 53 cm refers to the outer diameter of the grill, this misinformation is perpetuated bt the original manufacture. Bar be quick did not do do diligence, but i think it has an honest mistake.
I am more upset about the lack of a deflection plate as i think it should not be call a Komodo without one simply just a ceramic grill.
I will keep mine though and work on modding it to my liking. The Aldi one was a much better deal...
Live and learn i suppose.
