Works well. Ionmax app didn't work, or the UI was so different to the instructions I gave up. I ended up using the Tuya app. Instructions need to be improved. It did stop working once, and I thought I had to return it, but fortunately I just had to crawl into the roof space and restart it with my phone nearby. I was hoping to use it 24 hours, but it is noisy, so it runs 11AM-10PM. Combined with the 3 other Desiccant dehumidifiers the humidity is down to 50%RH, although in the morning it is 60-80% as both Ionmax dehumidifiers have been off overnight. I did install a few fans to save money, but they are even noiser and the overnight humidity outside is 77% so now don't run overnight. For a 1960s house there is no underfloor insulation, no wall insulation, and the foam roof insulation is significantly degraded. If I had a spare $30k I would fix the root problem, but for now, what I have works on average, just higher electricity bills in winter. I have roof-top solar.
