Brewing Types

The 3-in-1 design allows brewing with ground coffee, NS capsules, and DG capsules. This versatility lets you enjoy fresh espresso from your favorite blends. However, it only works with proprietary NS and DG capsules, limiting flexibility compared to machines that use Nespresso or other common capsules.

Capsule Compatibility Detailed Explanation

This machine is compatible with NS capsules and DG capsules, offering a variety of coffee choices. NS capsules refer to Nespresso-compatible capsules, which are popular for their rich aromas and convenience. DG capsules are compatible with Dolce Gusto, offering everything from rich espresso to sweet lattes. This 3-in-1 compatibility design allows you to choose freely according to personal taste, whether you prefer traditional coffee or modern convenience capsules.

Suitable Coffee Types

The ShareforU HS-8439 Mini Espresso Coffee Maker is best suited for brewing espresso and espresso-based drinks like americanos and lattes. The short 80ml brew capacity yields rich, concentrated espresso shots. But it may not be ideal for brewing larger amounts of drip coffee.

Coffee Quality

The fast brewing piston provides up to 9 bars of pressure for extracting robust, full-bodied espresso with thick crema. Exact flavor profile will depend on coffee used, but the end result should be premium cafe-style espresso.

Selecting Coffee Beans and Grind Size

The quality of espresso brewed with the ShareforU HS-8439 Mini Espresso Coffee Maker is greatly influenced by the choice of coffee beans and the grind size. For optimal results, select high-quality, freshly roasted beans and grind them to a fine espresso consistency just before brewing. The correct grind size ensures proper extraction and a balance between flavor, acidity, and body, enhancing the overall coffee experience.

Water Tank

The 80ml water tank capacity allows brewing 1-2 shots before refilling. The compact size means less water storage but more portability.


The mini, portable design allows true espresso brewing anywhere while traveling or outdoors. The combination of a fast brewing piston, silicone exterior, and dishwasher-safe cleanup in a mini machine makes this product stand out.

Additional Features

No extra features like timers or cup warming. Simple and focused on portable espresso brewing.


Specific noise levels are unknown but as a manual piston machine, noise should be minimal during brewing.


The FDA-approved silicone materials should provide safe, durable construction. As a manual machine without electronics, risks of electrical issues are also avoided.


The removable parts and silicone exterior are dishwasher safe for easy cleaning. The lack of complicated components or built-in grinders also reduces maintenance.


Minimal maintenance required outside of general cleaning and descaling when needed. No need for paper filters or other consumables.

To maintain optimal performance, it is recommended to clean the water tank and capsule container monthly with a specialized coffee machine cleaning solution to prevent limescale and grease buildup. Regularly check the silicone components for signs of damage or aging and replace them immediately if necessary. Such maintenance ensures consistent coffee taste and avoids potential machine failures.
