Owners who have lived with the Stagg EKG for years describe near-flawless daily reliability, precise degree-level temperature control, and a slow, restricted gooseneck pour that makes pour-over coffee and tea easy to control, all wrapped in a design people are happy to leave on the counter. A firmware update pushed in 2026 turned much of that goodwill sour, with a large group reporting the kettle now creeps toward its target temperature for what feels like forever compared to before. A separate, recurring minority reports base failures, rust spots, sticky dials, and other build lapses within a year or two of purchase, alongside gripes that the price buys more name and looks than substance. The same slow pour that pour-over fans praise frustrates anyone trying to fill a gaiwan, refill a Chemex, or make a quick cup of tea.
“But I bought one of these some time ago and – being the tea & coffee fiend that I am – have never once regretted it. If you're trying to save money and could use an electric kettle, this will treat you well.”— thehudsonswerve on Reddit
“the kettle is a Fellow Corvo EKG (could hold more water, but pretty, silent and fine temp control)”— kekstee on Reddit
“I switched to the Corvo after my Stagg broke. I was quite disappointed by the pour quality of the Corvo, though.”— @ThijsVogels on YouTube
“I got my Fellow Stagg EKG used at a discount from a coworker. But now that I'm accustomed to the convenience, I probably would still pay full price for it now if I had to replace it.”— magus-21 on Reddit
“I recently made the switch to an electric kettle myself and it is so worth it imo, especially for how fast it heats up and being able to set a specific temperature. The one I have (Fellow Stagg EKG) you can even hold the set temperature for up to an hour”— magicalmarshmallows on Reddit
“Fellow Stagg EKG Kettle: I mean, it looks nice, sure. But my first one had a defective base that required email after email after email to convince the company to activate my warranty. Just get the Bonavita. It does the same thing and is often on sale.”— WowDotes on Reddit
Real owners lean toward the Fellow Corvo EKG: 73% of 44 owners recommend it, vs 54% of 281 for the Fellow Stagg EKG Pro.
Owners point the Fellow Corvo EKG at tea drinkers who want a fast, non-gooseneck pour, and gongfu and gaiwan brewers needing precise low temps.
Owners point the Fellow Stagg EKG Pro at pourover coffee brewers who want precise, controllable temperature and a slow, steady pour, and daily coffee or tea drinkers who value a hold function that keeps water at temp for later.
The most-cited downside of the Fellow Corvo EKG is glitchy temperature readings and overshoot. For the Fellow Stagg EKG Pro, it's a 2026 firmware update slowed the glide into target temperature dramatically, with a large wave of owners saying it now takes far longer to heat than it used to.
