Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Decent as an oven, worthless as a toaster.

I hate giving negative reviews, but this is one thing I have to rant about. I've had this "toaster" oven for seven months now, and I've finally give up and am now searching for something more akin to the old "fire hazard" model I had a decade ago. The quartz bar technology in this model takes forever to heat up, and in the case of toasting, never truly toasts-- it just warms the item up, never making it truly crispy or golden brown (unless you put it in for multiple cycles, in which case, it dehydrates your item completely and *still* doesn't make it any browner). As a mini-oven, it does work, and the convection is nice, but be prepared for insanely long preheat times.
