What owners single out
Bean inconsistency frustrates buyers most, echoing video reviewers' concerns about the machine's sensitivity to grind and technique.
In their words
“I bought the dual boiler over two years ago now and it has been used daily ever since for amazing flat white's in a morning. There's not a lot to dislike about this machine - gets upto temperature quickly, pulls great shots & foams the milk to perfection. The only issue is running the descale cycle can cause the steam wand to stop working so I don't bother anymore, opting to use the filter instead”
Jonathan · verified purchase · sageappliances.com
“Consistently great, providing you descale and clean when it tells you on its wee screen. That is a bit of a faff and takes around 2 hrs every 6wks. But any good piece of kit needs looking after. The issue is coffee beans. Complete inconsistency is the norm. It doesn’t matter whether you buy top of the range Lavazza beans or £80kg from your local roaster. I use a separate Sage grinder, which allows”
