Bests & Worsts Reviews from Amazon

I like everything of this Toaster Oven but NOT the temperature! I only use it 4-5 times in the last few month and just couple days ago I found out the temperature just not working properly as it should. I had two pieces of Mackerel, after 35 minutes at 400 still not done so I add another 15 minutes at 450 and it started to getting some brown on the surface. 50 minutes for two pieces of 120-130g of Mackerel? Not very impress with this product at all.
