VonBueren
Cold packs square

The VonBueren cool pack is a practical and useful everyday item that is particularly indispensable on hot days. Thanks to its square design with engraving, it fits perfectly in various cooler bags. Thanks to the engraving, it can also be used in open containers so that it can also cool individual bottles without any problems. However, it should be noted that the specified cooling capacity depends on the respective ambient temperature, e.g. the temperature of the cooler bag to be used.

  • Practical design
  • Easy handling
  • Compact size
  • Cooling capacity dependent on ambient temperature

The test

General information

We took a close look at the product and tested it in practice. In the following, we take a closer look at the features and impressions. From the packaging, materials and quality to the range of functions and handling, the product is subjected to our test procedure.

To give you a quick overview, we work with a points system. The maximum achievable score per area is 100 points. The final overall score is calculated from the average of all tested features, taking into account the respective weighting.

The first impression

Packaging and contents

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?

The cool packs are supplied packed in a sturdy cardboard box. Depending on the product set selected, 4 batteries are shrink-wrapped and packaged in plastic film . A red plastic clip prevents the batteries from slipping so that they are securely tied up. Thanks to the sturdy cardboard box and the very robust material of the batteries, damage is virtually impossible. The packaging in plastic film is necessary because of the liquid. A multilingual instruction manual with important hazard warnings is included with the product, even if the operation is self-explanatory.

The cool packs are compact and square so that they can be easily stacked or stored next to each other. Thanks to the engraving, they can also be partially inserted into each other, albeit only to a limited extent. Nevertheless, they are very convenient to handle, especially as they are also easy to transport due to their compact size. The material is very robust and can withstand hard knocks or accidental drops. The closure is firm so that it remains tight even under pressure .

Does the manufacturer keep its advertising promises?

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.

In the practical test, the tightness of the cool packs was tested first. To do this, slight pressure was applied, as can occur during transport in a cooler bag or through the effect of weight. This worked without any problems and the batteries remained tight. The weight is approx. 200 g as stated, individual deviations of a few grams are acceptable and do not impair the function of the cool packs. The material is very stable and has withstood rough handling without visible scratches, damage or even leaks. The edges are pleasantly smooth and nowhere sharp or pointed, so that no damage or injuries are to be expected. Even when exposed to heat, e.g. when freezing or defrosting, no damage or deformation was recognisable, meaning that the product fully met all 5 criteria in the practical test.

Price/performance ratio

and ratings from consumers

Finally, we analyse 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? We also look at the consumer reviews and check whether the critical and positive reviews are actually justified.

At the time of testing, the product had not been listed on Amazon for long enough. Therefore, the existing reviews do not sufficiently reflect the advantages and disadvantages of the product, so this point is neglected in the evaluation.

Prices of up to €11.95 are charged on the Internet for equivalent products. Very cheap products are available from as little as €6.99 . The VonBueren® cool packs are therefore currently in the middle price segment with a price of €8.77. For the quality and performance received, the price-performance ratio is very good.
