The Mueller Ultra M99S was one of the items we tested for the best electric tea kettle before. And although it didn’t beat the Cuisinart CPK-17 PerfecTemp in the said roundup, it is beautiful and sensible in its own way. The lack of numerous buttons makes it a practical choice for many users who simply want hot water in a minute. A single switch located in its handle offers pure simplicity and excellent functionality.
