Well I have had the Waterdrop K19 countertop RO system for a while now. It seems a well put together system, unknown how well the filter cartridge will last until a year has elapsed.
The hot water is definitely way way cooler than the hot water the Osmio Zero produces…which is slightly irritating, as my americanos are just too cool, I don’t want a 10 second big gulp. So drinks always have to be topped off in the microwave.
P.S. This is irritating enough that I briefly contemplated putting a kettle back on the counter, but I don’t want to do that.
P.P.S. a lot of what the influencers say about hot water is bollocks
