Needed a new replacement 'toaster' oven with a steam function. Was hesitant since all reviews here appeared to be 'compensated, and very little info/reviews on YouTube or social media. Well, I'm quite impressed with this unit. Steam is very efficient, convection fan is quiet and heat up and cooking times are faster. Easy to operate and clean(all surfaces are smooth inside and out). It appeared that all the controls were complicated but it very easy to setup and use. I like the way the water tank is situated, but would be nice to know the water level from some indicator outside. Very nice build quality, design and ease of operation. Highly recommend if you want steam cooking and convection operation. Inside dimensions are approx 14"W x 7"D x 6"H.
