It's good so far, but only been in for a couple of weeks. Please note it needs to have an operating temperature of above 5degC. We've got this in an external annexe which is colder than rest of house but it's working fine despite having a lower ambient temperature. If not connected to mains (ours isn't currently) then you need to empty the codenser tank every dry. So if you're considering this, make sure you're ok with that or connecting it to drain, which we are doing once we rearrange our kitchen.
