@rotuts the picture below shows you where my Breville sits. I just pre-heated it to 325F and was able to quickly touch one side of the oven without burning myself. The other side was hotter. I have a cutting board on top of my Breville and have no problems with the cupboard above it.
I always cover my dough when proofing, i have not thought to do so otherwise. It is also what the manual recommends. The temperature has been factory set at 85F, but can be adjusted to anywhere between 80 and 100. I have checked the temperature with an oven thermometer and it is accurate.
The air fry basket was easy to clean. I just use soap and water, but then I haven't used that function much.
