I got it for use in a Nespresso Vertuo Plus coffee machine.
It worked perfectly, exactly like the Nespresso descaling kit,
with the difference that it costs about 10 euros for 5 uses instead of the same price for 2 uses.
It's worth it and does the job.
I don't know why people write in the comments that it is 400ml when both the title, product description, and the product itself are 500ml.

I use it for descaling my Delonghi EC685 and honestly, I've noticed a difference in the overall performance of the machine after each cleaning. The water flow and extraction seem more stable and generally the machine works more smoothly. I also liked that it doesn't leave a strong smell or strange taste after the rinse cycle, something I had experienced with more generic cleaners.
The fact that it is a ready-to-use liquid makes the process very easy and overall it seems like a safer choice for the Dedica compared to harsher descalers.
It is definitely a bit more expensive than other solutions, but personally I prefer to properly maintain my machine rather than save a few euros.

Does what is states!
It could be cheeper. I will probably use the generic descaler once warranty ends on espresso machine

It is an excellent product as the previous reviewers have said. I will also say that I used it in a Dolce Gusto espresso machine. What went through the machine and cleaned it, I poured into the kettle and it became like new.

When my machine gives me a message that it needs descaling, I use the dose indicated by the device and everything is fine…
I've been using it for 3 years now and everything works like clockwork…

For all brands of espresso coffee machines. It is also suitable for French press coffee makers. If over time you feel that the coffee is not as good as it used to be, it's because you haven't descaled (search for 'desalting' on YouTube and you'll find many instructional videos).

I don't know if it really does anything. Supposedly, in our area the water doesn't have a lot of limescale and every month it needs descaling.

When the coffee machine needs descaling, the coffee comes out a bit burnt. With this, it returns to normal so I imagine it does its job properly. I guess the lifespan of the coffee machine will show. Please lower your price.

It does the job but the secret is not to use tap water in your coffee makers. Only bottled water and even better, check for the mineral content it contains.

It does a very good job and immediately! I used to use illy powder before but I won't change again. The price and the result are worth it!

I have been buying this specific cleaner for 3 years now, as long as I have had the coffee machine. It does a very good job.

Very effective product!!!
It does exactly what it was made to do to the fullest extent!!
I have been using it for four years and it always gives excellent results.
Used for descaling in a De'Longhi Magnifica E3000 machine!!
Don't hesitate at all!!
P.S.: Previously, the bottle was 500ml with a measuring cap for 5 uses of 100ml each time and priced around 7-8€.
Unfortunately, now it comes in a 400ml bottle for four uses of 100ml, but costing an extra 4-5€.

Very easy to use, effective and more economical compared to the small Delonghi package included in the original packaging.

the product had a dispenser with 5 doses but only 4 were made while the price also increased meanwhile it was 500 ML with 100 ML per dose

I tried it on a glass bottle that had collected limescale and I had stopped using it because of that, and it cleaned it in seconds. I highly recommend it

I followed some guides on YouTube and not Delonghi videos or the manual. Time will tell. I also used it in a kettle and it cleaned it perfectly. Worth it up to 10-12€

It does its job perfectly. I cleaned the coffee maker with one dose and what I collected I poured into the water heater and it made it shine from scale without any issues.

The product is used in a De'Longhi coffee machine for descaling and it really does an excellent job. Although quite a bit of scale accumulates in the machine from one descaling to another, with the most noticeable problem being in the water tank, immediately after the descaling process everything shines!

You simply follow the instructions and it cleans the machine perfectly, it becomes almost like new, the water flow has fully returned.

Using it on a De'Longhi Dedica machine that hadn't been descaled for years (since it was purchased) restored the water flow to how it was when I bought it and greatly improved the taste of the coffee.

Excellent, the coffee maker's pot had changed color from the minerals and after the application it became like new just like everything else I used it on, e.g., kettle, pot

Excellent.
It removes all salts from everywhere.
The kettles really shone with half a lid and half a liter of water.
The SMEG coffee makers (French and espresso) were effectively cleaned and the alarms turned off.

Excellent, both for the espresso machine I have and for the filter coffee maker. It does the job immediately without any odors. Highly effective, I highly recommend it.

Effective product. After 2 passes from the coffee maker, instead of throwing it away, I threw it in the kettle without turning it on and left it for 5 minutes. The kettle not only shined but also maintained its shine for weeks. In the past, I would put water and vinegar in it and turn it on. It would clean, but apparently it didn't completely clean the salt deposits because it would start accumulating salt again within a week...

I used this specific product for descaling my illy iperespresso coffee machine. So far, I am very satisfied. Not only did it effectively unclog the tubes, but it also improved the performance. Specifically, after descaling, the amount of coffee has increased per cup without altering the taste. I will use it in the future for my French press coffee maker to see if it has the same results there. I will return with a new review. Lastly, I appreciate the included dosing meter on the bottle, which really helps because you know the exact amount of water to add.

Effective, it removed the limescale from the espresso machine without leaving any smell or altering the taste

Very effective! The espresso machine scales are completely gone. I am very satisfied with this and give it 5 stars!

It did a great job without leaving a bad aftertaste in the coffee (it needs to be cleaned thoroughly as the instructions say after use obviously)

I got it for Nespresso, it did the same job as the official product (using the equivalent amount). It's worth it.

Practical bottle with liquid descaler for 4 uses, with a dosimeter on the side for accurate measurement per use.
