“It still gets up to temp as fast as it did. Can be a couple degrees off, but I've been extremely happy with it through the years.”— [deleted] on Reddit
“Bonavita gooseneck kettle at 198 degrees using a Hario v60. Once you start drinking good coffee you realize the burnt offerings of chain locations”— seoulbrova on Reddit
“compared to the Bonavita kettle that died on me. (Edit: They're good quality, but if you leave them plugged in 24/7 a fuse in the base tends to blow, at least in Europe.)”— joakims on Reddit
“The COSORI has been awesome so far - it has 5 selectable temps, a hold option which is nice if you're preheating a vessel for espresso or something, and it overall just feels like a quality product that was well-built. Would definitely recommend :)”— purring_parsley on Reddit
“It adds a special touch to the kitchen and works flawlessly, of course.”— Organization-Silky79 on Reddit
“I hated the Cosori. It would sputter out of the spout and splatter my grinds everywhere in my pour over (V60). Then the handle came loose after a few months.”— @_Code.Pilot_ on YouTube
