The reason to own a glass kettle is that you can watch the water and see exactly what it is sitting in. Cosori takes that second part as far as any kettle here: the borosilicate body, the spout filter and the inner lid are the surfaces the water meets, with no plastic anywhere in the path. A lot of kettles on this page say BPA-free; this one can say plastic-free, and steam that condenses on a steel lid drips back into steel rather than into a plastic dome.
That is what puts it at the top, but it is not the whole case. The 1,500-watt element brings two cups to a boil in under three minutes, 1.7 liters fills a French press and two mugs with room to spare, and the lid swings open wide enough to get a hand inside for the rinse. It also costs less than several kettles here that offer no more.
The habit worth forming is checking the shut-off. Most units click off the moment the water rolls, some don't, and a kettle that keeps boiling after the switch has had its day is a kettle that shouldn't be left alone. Watch it through the first week — it is the one safety feature you cannot verify from a specification.
Cleaning is where the wide mouth pays off. Glass shows every mineral deposit, and being able to see and reach the bottom means you catch scale before it becomes a chalky ring; a little vinegar and a soak handles it. The body is hand wash only, which goes for every kettle in this group, but it is worth knowing before the first wash rather than after.
