I have had it for 2 years. A very controversial purchase. It's a love-hate relationship. If you learn how to operate it, it will make you good coffee, but it also has various "quirks" that can easily frustrate you. By "good coffee" I mean better than 100 euro machines. I understand that a professional might give it a bad rating if they expect semi-professional equipment, but I find it hard to believe that they couldn't learn how to use it as it is.
It doesn't have automatic functions or timers. For example, it dispenses water for as long as you hold the button. I like it because it gives me more control, but for someone less experienced, it may be the reason for inconsistent results. The boiler builds up much more pressure than any household machine I have seen and releases steam with a lot of pressure. The steam wand, for example, makes much better froth than the low-cost ones I have seen. Also, it is one of the few steam wands that can remove the "assist" extension that draws air and make froth only with the pressure of the steam (only machines of a different economic level have this).
The grinder is a simple burr grinder, but it makes A LOT of noise! You have to shout to be able to talk over the noise. If you live with other people, it will annoy them. Also, the grind settings are a bit funny for espresso. Out of the 20 settings, only 1-2 are suitable for espresso (and those are for the pressurized basket it has), and another 2-3 are for filter coffee. Anything higher doesn't work because the grind becomes too inconsistent. It retains about 2 grams of coffee during grinding, but you can "tap" it and shake it a bit to get almost all the coffee out. The portafilter that comes with the machine is the pressurized one (with the hole), so the grind size may not matter that much in the end. But it is definitely better than any pre-ground coffee. I definitely recommend replacing the plastic tamper, which seems to be made for a completely different basket diameter. Get a 58mm one.
It also makes noise and shakes a lot during extraction. Sometimes the cup underneath moves due to the vibration. The construction is plasticky. It looks and feels sturdy and of good quality, but in terms of design, it feels more like a children's toy. Also, I feel like it is bulkier than it needs to be. The red color looks nice on the countertop, especially if you have other red appliances.
That's it. For the 150 euros I paid for it, I consider it a decent-good purchase because if you were to look at separate prices for a burr grinder and an espresso machine with some "professional" features, it would be hard to find a combination for less than 400 euros.
Edit: This basket: [link] is non-pressurized and fits perfectly in the portafilter, it just doesn't lock like the original one. However, with the machine's grinder, you won't achieve a satisfactory grind for a non-pressurized basket. It needs to be finer. It may be possible to modify the grinder like the Delonghi here (link), but I haven't done it yet
