Really happy with this purchase
Been using this boiler for a few weeks now and it's become part of our daily routine. The finish holds up well and hasn't shown any wear after regular use. Can't imagine going back to what we had before.
Great addition to the household setup
The build quality on this boiler feels sturdier than others I've owned in this price range. It's quiet, easy to clean, and the controls are intuitive even for someone who isn't techy. Great value for what you get.
Underwhelmed by this one
Unfortunately this boiler hasn't held up the way I hoped. It started making a strange noise within the first month and support has been slow to help. Considering returning it if things don't improve.
