Sage The Smart Oven Pro BOV820BSS 5 "A joy to use." Julie 10 March 2018 I got this to replace a different compact oven which did not have any smart features so was basic and of not such great quality. This Sage Smart oven is a breeze to use and a lot of thought has been put into it. I have grilled and baked all sorts and everything has come out perfectly which has been quite a surprise, thus showing it’s smart capabilities and constant monitoring. It takes most of the regular size tins BUT not all. Any trays, as in, muffin, buns and any flat trays are too big. There are smaller ones but they leave a lot of unused space so not really practical. Still love the oven.
