That's true and something I pointed out to them when they asked for website proofreading before release.My Hopper io manual shows a temperature range of 150-230° Celsius. The website shows two different temperature ranges, 130-230 and 180-230. From my experience using the io it seems to line up pretty well with the 150-230 listed in the manual. It would be nice if we could get official confirmation of the actual temperature range from @Hopper Labs or maybe even @VGOODIEZ . Hopper Labs should probably update their website too.
Maybe there's batches of all variations out there. Mine does seem to do something like 180-230, I'm away from home and using the legacy now and T1 130°C is wildly far from what my io does
