Oven heats up very quickly compared with my previous range.  The air fryer and convection feature work very well - I like having both these options.  The burners on the stove top also heat up quickly and heat food/boil water very fast, which is great.  Two wishes:  I would prefer the knobs for the burners to be metal or a much harder plastic - they feel a little cheap; the air fryer would be so much better in the top oven.
