The brand in question was a Tiffany turbo oven. I feel somewhat aggrieved that I was sold something which was implied to be a (KK)TO roaster rather than what it actually was, but the price was low enough that it might not be right of me to feel moreso. Essentially, the glass top should never sit directly on the pasta pot lid. When you look at the videos of all of KK's ovens, they either have 3 black heatproof buffer bits, or a blue silicon ring. This had neither, and although independently acceptable, the PC transformer connecting to the motor via bare wires. The roaster then involved a pair of brick pairs to raise the pot to the right height, and the TO resting on the top of the pot. So probably cracked from tiny movements against the pot, and flew outward because of the pressure of sitting on the pot. The glass also had a layer of brown oil. However, having had tempered glass shatter on me before (grill glass), it tells me two things. 1) KK spent a heap of time trying to make sure his roasting setup was safe, while using a turbo oven outside warrantied usage and in a potentially dangerous manner. 2) Always wear safety specs or at a minimum, sunglasses with hardened lenses (eg. oakleys) around hot glass @ ~230C. 3) Turbo oven glass should be cleaned regularly to prevent oil buildup. Sadly with the back injury I'm going to be selling my beloved Domus Galatea even to pay rent + rehab costs, so while I'm not earning at the moment I can't afford KK's lovely parts. I would say that the Tiffany TO rated at 1200-1400W was a lovely and well-timed roasting machine, but that the Homemaker unit I've found is a very bright yellow halogen element, so with the guard removed (to prevent 30 minute roasts) I think I'm as happy as I can be with the setup at the moment. As there's no insert I'm roasting on bare metal with a 15.5L volume (295mm diameter, 230mm height), and agitating directly, with a small vertical cut for chaff (sadly large enough for the odd baby yirgabeany to pop out), and a slightly bent/non-rigid motor shaft makes the shaft/agitator quite loud. Totally agree with beanflying's info - not cause for alarm, but cause for caution. Manufacturing fault, poor maintenance or no, if you get eye damage from it, no judge or jury is going to award you compensation for using a turbo-oven like this. Total cost of the incident was about $450, including replacement TO and stablising the pan so it couldn't do this again. I don't think it's the fault of the Tiffany TO, but of the seller's somewhat bodgy setup. While I appreciate the price he sold it at, it's been an experience I could ill afford.
