These are the same products, there are no differences in the functionality of the Google Nest Mini, but the Google Nest Mini 2 are better, because they have better speakers. They all have Wi-Fi too :). Be careful when placing on coated furniture, the rubber underside of the Google Nest Mini can stick so much to coated surfaces that it can happen that a bad coating tears when lifting the Google Nest Mini (happened to me, these rubber surfaces at the bottom seem to really stick to coated surfaces, which of course they don't but better put something under there).
