I had these counter tops hot water dispensers for several uears. First one was quie cheap, and when it died I replaced it with a Klarstein one. Loved that. Tank held 4 litres of water, so did not re-filling often. Gave me a choice of temperatures (although TBH, once th noveltyu had passed I tended just to keep setting at the hottest. Also gave me different amounts being automatically dispenses.
I would turn it off at the plug when I went to bed, and back on in the morning. Had - immediately, - water for my tea. WOuldplace mug or small tea pot on the drip trau push button and then go away to make my porridge whilst it was happening. By taking away the drip tray I could easily put a saucepan underneath the dispensing spout. Had a filter so no prponlem in my very hard water area. Quite slow in displensing, so never any worries about scalding.
When I had my kitchen re-fitted ealier this year, I decided to go for a hot water tap - and this is brilliant. With that it is all so simple anything from a mug to a large saucepan, to a hot water bottle, etc. etc. Only works when I am actually pressing down on than button, - so no worries about scalds, etc. So I now have exactly the amount of boiling hot water I need at the push of a buttong, no re=filling anything, no measuring and no waiting. No kettle to worry bout ropping or spilling - so easy and very safe to use.
