Grundig KSM 4330: what works, what doesn't?
What works well
- Very slim: at only 14.4 cm wide one of the most space-saving portafilter machines, ideal for narrow kitchen runs
- Touch display with memory: preprogrammed single and double espresso; the memory function saves your individual water amount
- Integrated cup warmer: preheated cups on top improve extraction and drinking temperature
- Automatic care programmes: cleaning and descaling programmes support hygiene without manual fiddling
- Strong 1,628 W: high heating power ensures a quick heat-up time and stable brewing temperature
Points of criticism
- Small water tank: 1.1 litres is tight for a family or frequent milk drinks, so plan on refilling more often
- No grinder: without an integrated mill you need a separate coffee grinder or pre-ground espresso
- Touch instead of feel: if you prefer physical buttons and dials, you have to get used to operation via a sensor panel

Build quality & everyday use
What carries the Grundig KSM 4330 in everyday use: very slim (at only 14.4 cm wide one of the most space-saving portafilter machines, ideal for narrow kitchen runs) and touch display with memory (preprogrammed single and double espresso; the memory function saves your individual water amount). We have to be honest about the weaknesses: small water tank. 1.1 litres is tight for a family or frequent milk drinks, so plan on refilling more often.
If you set the device up to save space, make sure it stands on a stable, level surface with some air around it. This protects the mechanics and electronics in continuous use.
