The temperature range is from 37 ° C to above 275 ° C, which is higher than most ovens. The temperature rise is fast enough, I measured 3mn50 to 100 ° C 6mn50 to 200 ° C and 250 ° C for 10 minutes with convection. The manual says 5 minutes to 250 ° C with the grill + sole mode. The oven goes beyond, but my probe is limited to 250 ° C. Even at this temperature, does not burn rapidly affecting the furnace, indicating good insulation.
The temperature stability is good, with about 6 ° C on either side of the selected temperature. Thus, to position 4, it oscillates between 139 and 151 ° C (145 +/- 6 ° C). For comparison, my old toaster oven with natural convection Seb had a magnitude of more than 25 ° C.
Quartz Resistors are the big advantage of this model and allow to brown much better than a resistance. The roast chicken spit spring with exactly the same appearance as at the cook.
The selling model is actually 351 and not 350, which adds an adjustable timer up to 2 hours. It is built tough and rather aesthetic, which does not spoil anything.
I do not agree at all with the negative remark about the only locations of Mr. Martin BERNARD grids. These are reversible, making 4 height levels in the oven, which is good enough. The rating given by the user is also preposterous for a camera of this quality.
The only real flaw of this oven is the noise generated by the vibrations of the fan, that is, it must be admitted, rather painful. That is why I take him a star. But in its price range, it has no other competitor in France that the Roller Grill RTQ341, and as long as the Breville brand does not sell its "Smart Oven" in Europe.
Amazon was very responsive as usual, but UPS as poor habit, the driver did not before passing and not passing calling on the date indicated.
