I have used this dish every day since the first prototypes shipped and couldn’t be happier. The attention to detail on every aspect is bar none. The precise machining allows the comets to glide and the material to evenly vaporize. The polishing makes it look attractive and easy to clean.
The SiC material by far is my preferred material for my rigs and you can rest assured that D-nail is using the purist, lab tested material. The vigorous testing shows by how long the product holds up. It is not fragile, easy to heat, heats evenly, maintains heat, and best of all, it does not absorb any material or break down.
Ceramic and quartz are fragile. Ceramic, quartz, and titanium tend to leach material and can fowl up the flavor after a while of heavy use.
I can say that we have used the same Sic dish daily with multiple people using it, with no complaints! Everyone is impressed with how easy it is to maintain and how they can taste the full flavor of their product.
I would suggest looking at the nimbus if you are considering using comets. I will add a review to the nimbus SiC as well. I own both products and highly suggest either model. I look at the nimbus as the newest version of the halo.
