About Us

Prüfengel offers authentic consumer tests in which real users share their experiences with products. Our tests are based on practical applications in everyday life and reflect the opinions of consumers. As we focus on consumer tests, we do not carry out any material, long-term or laboratory tests. The tests are carried out by 1-2 independent consumers over a period of 7-14 days. The exact test conditions can be viewed in the test plan of the respective test report – click here to go directly to the test plan.

Manufacturers provide the tested products free of charge. We charge a one-off test fee for carrying out the tests. In addition, manufacturers pay an annual licence fee for the use of the Prüfengel seal. We also receive a commission for linking to manufacturers’ websites. These remunerations have no influence on our test results or ratings.

We guarantee transparency and a fair evaluation. For a detailed insight into our comprehensive evaluation process, please click here.

The first impression

Packaging and contents

ℹ️ Here we take a closer look at packaging. Sustainability is becoming an increasingly important factor. In addition, adequate protection of the product must of course also be guaranteed. Are the contents of the packaging complete and does the manufacturer make it as easy as possible for me to use the product straight away?

Elektrischer Allesschneider mit Zubehör
Electric all-purpose slicer
with accessories

The all-purpose slicer leaves a positive impression in terms of appearance and workmanship. The appealing retro design with stainless steel housing fits well into any modern kitchen. The workmanship is very good, with clean transitions and no visible scratches, dents or sharp edges. The appliance is extremely robust and suggests a long service life , although the manufacturer does not provide any specific information on sustainability. The blades are already pre-lubricated so that the appliance is ready for use immediately after a quick clean. However, the grease has spread slightly in the packaging.

This is what our practical test showed

Does the manufacturer keep its advertising promises?

ℹ️ Our practical test has the highest relevance and therefore weighting. Here, the product has to undergo a wide range of criteria and tests. We check the functions and product promises of the test article.

*The maximum score is 100 points

The two different blades, one for meat and one for bread, proved to be sharp and precise. Both raw and cooked meat was cut effortlessly and without fraying or messy edges. The blade is easy to remove, allowing for thorough cleaning. The housing can be easily wiped clean with a damp cloth . The manufacturer has equipped the appliance with an effective safety mechanism that prevents the blade from being switched on if the safety guard is not properly closed. The non-slip feet also ensure a secure stand. The electric all-purpose slicer is equipped with a 150 watt motor . The on/off switch and cutting height adjustment function perfectly and are easy to operate. The collection container for the clippings ensures tidiness and cleanliness. Only the slider for the cutting thickness is a little stiff, but has the positive side effect that it is not so easy to adjust.

Price/performance ratio

and ratings from consumers

ℹ️ Finally, we examine how the product compares to the competition. Can it keep up with the competition in terms of price and quality? Would we generally recommend buying it?

CriterionRemarkScore achieved*
Price / performance ratioVery good90 points
Rating cut4.2 out of 5.0 on Amazon60 points
Total75 points
Weighting: 15%
*The maximum score is 100 points

On the Amazon platform, consumers rate the product with an average of 4.2 stars. The volume and the somewhat stiff slider are often criticized. However, the product impresses with its powerful cutting performance, safety and ease of cleaning. Our practical test confirmed the good cutting qualities for meat and bread, while the all-purpose slicer was easy to handle overall.

Prices of up to € 280 are charged on the Internet for equivalent products. Very affordable products are available from as little as €45 . The Twinzee electric all-purpose slicer is therefore currently in the lower price segment with a price of €89.99. For the quality and performance received, the price-performance ratio is very good.
