For most coffees you're going to want to be a little higher, around 198-203 degrees for proper extraction.

Very good choice to never place it in the dishwasher, it takes just a few seconds to clean and it lasts a lot longer

The standard recommendation for the Aeropress, including from Adler himself, is to use 175F water, much less hot than you'd use in other preparation methods.

In Seattle at least, there is near-universal consensus among every coffee shop I've been to using an Aeropress that 175 is much too low. Most go closer to 200.

What’s your definition of “proper”? You get a different flavor profile if you vary the water temperature. My favorite for single origin light roasts is very fine grind, not too much 170–180° water, and short steep time. It requires somewhat more beans to get strong coffee compared to a brew using more, hotter water and a long steep time, but the resulting cup of coffee is much tastier IMO.
