In general, individuals who purchase electric kettles are tea lovers and they use their electric kettles every day.  The PerfectTemp Cordless Electric Kettle is a tea lover's perfect companion.  First, it recognizes that there are different types of teas and that each tea requires its own temperature and duration for boiling.  Second, it keeps the water warm if other responsibilities demand attention thereby ensuring that a perfect cup of tea is ready when the tea lover is ready.  I have tried many electric kettles and this kettle is by far the best kettle because it recognizes the diversity of tea leaves and the busy life of the tea drinker.
