We bought one of these, cause I'm a bloke and love gadgets... Once the initial run off has done... Then it is very suitable for bottles and saves a fortune in electricty.... only uses around 800w per boil, where as the average kettle uses 2kw per boil..... Over a year it will add up quite quicky.... Only disadvantage is it's noisey.... We still prefer it over a kettle anyday... as its instant, no getting up at 0230am and waiting (what feels like forever) to sort out a bottle or warm one up.... Hope this sways your mind back.... (think of the savings)... lol R
