I've purchased a number of Breville appliances over the years, and despite having had a varied results with product reliability, I took a chance and gave this microwave a try. To begin, this is not a convection microwave. It is not new technology. It is a regular, relatively underpowered microwave at only 900w. The "crisping" feature is nothing more than a round metal pan with a non-stick coating that sits inside the microwave. If you want foods to remain crisp on the bottom, you have to place them in the metal pan, turning them over mid-way through cooking. At least, that is how it is supposed to work. In reality, this crisping pan does not crisp anything at all. I've made numerous attempts, to no avail. Basically, the microwave makes the pan get really hot. I'm not impressed.
Like many others, no doubt, I was lured in by it's attractive design. Speaking of the design- there is no numeric keypad to enter the amount of time you want to cook something. Instead, there is a rather delicate metal looking dial. You twist this dial, and there are little clicks. The screen increases the cooking time with each click. Unfortunately, this dial malfunctioned right out of the box on my first unit. No matter how slow or how fast I turned the dial, the time on the screen would increase to about 1 min, then all of a sudden jump to 7 mins, or 5 mins. Very erratic and extremely annoying. Setting the cooking time is the most basic of features, and this unit fails miserably at it.
I returned the first microwave, and received a replacement unit, which, malfunctioned in the very same way right as soon as I plugged it in. Clearly this is an issue. I contacted Breville USA about this, and was told they have had no complaints, and that this is a sturdy model, which should last at least a year. A year? My old Samsung lasted 15+ years with daily use.
What you have here is basically a $99 underpowered microwave, with a $250 metal non-stick "crisping" pan as a gimmick. At least, that is how I see it. it is beautiful to look at, and has some fairly clever features, although some of which are bizarre. For instance, there is a narrow strip along the right inside edge after you open the microwave door, on which there are buttons for pre-set cooking times/heat levels. I have no idea why they put the buttons inside the microwave, other than to have a cleaner appearance on the front. It is very bizarre.
You can do much better. Get a regular microwave, and maybe one of Breville's Smart Ovens (countertop oven), and problem solved. In the end, you want a powerful, reliable microwave, with an easy to use control panel. This is not it.
