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.

Echocube
Baby Safety Locks

The Echocube Baby Safety Locks have been specially developed for securing furniture and cupboards to prevent small children from reaching dangerous contents. They offer a simple solution to block access to cupboards, drawers and other potentially dangerous areas. The uncomplicated installation, good adhesion to various surfaces and hard-wearing material make the product a practical choice for parents. A particularly positive feature is the light locking mechanism, which makes it easy to use. However, when it came to cleaning, we noticed that this was somewhat more difficult than expected, which can be less convenient in practice. Overall, however, the product offers a high level of safety and good functionality for households with small children.

  • Quick & easy installation
  • Lightweight locking mechanism
  • Safety factor in everyday life
  • Good adhesion
  • Cleaning somewhat more difficult with coarse soiling

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?

In our practical test, the Echocube Baby Safety Lock was convincing in all areas tested. Installation of the product was extremely straightforward and quick. Thanks to the self-adhesive mechanism, no additional assembly was required, which makes handling particularly easy. The adhesive strength on various surfaces is particularly noteworthy: The latches hold equally well on wood, metal and plastic and show no signs of peeling even after several days.

In the child safety test, we found that the product showed no signs of wear or weaknesses. It offers a high level of security against unintentional opening by children. Furthermore, there were no sharp edges or loose parts that could pose a danger. There was one small negative point when it came to cleaning: Although the surface of the product is largely easy to clean, stubborn stains are more difficult to remove, which makes cleaning a little more difficult. Overall, however, the product fulfils expectations and offers a solid household safety solution.

On the Amazon platform, consumers rate the product with an average of 4.4 stars. In individual cases, the only criticism is that the child safety locks are somewhat more difficult to clean. On the other hand, the simple installation and good adhesion are emphasised positively. In our practical test, we were able to confirm that the easy handling of the Baby Safety Locks is well received by customers. However, consumer criticism of the difficulty of cleaning was not justified to the same extent.

Prices of up to €26.99 are charged on the Internet for equivalent products. Very affordable products are available from as little as €5.99 . The Baby Safety Locks from Echocube are therefore currently in the lower price segment with a price of €9.99. For the quality and performance received, the price-performance ratio is very good.
