but power levels are amazing for reheating (around 50%) and defrosting (around 25%)

and I would argue these are two of the major reasons to use a microwave

Power levels are essential to me. I thought all microwave ovens were borderline useless to heat/cook food unless you don't care about how the food comes out. Learning to use power levels really improved the usefulness of the machine.

Particularly for defrosting things and softening butter.

Does cooking for 4 minutes at 50% really yield a significant difference to compared to 2 minutes at 100% then waiting 2 minutes? I'm curious.

[Tostino]

Yes, it's a massive difference.
