P1 - Product packaging & sustainability
Category description
This test category examines the quality and sustainability of the original packaging in all relevant dimensions: protective effect, information content, material ecology, volume efficiency and sensory safety. It is assessed whether the packaging reliably protects the product from damage, provides all necessary information clearly and completely, uses resources efficiently and enables environmentally friendly disposal. High-quality packaging not only contributes to product safety, but also strengthens consumer confidence and reduces environmental burdens.
Unternehmen & Kommunikation
Category description
The evaluation of a manufacturer/dealer includes the legal form, which provides information on liability and capital structure, as well as the location, which has an influence on communication, in particular whether communication can be carried out in German and without time difference. It is also checked how easily important information such as imprint or customer reviews is accessible and whether a professional website is available. The production location is analysed in terms of standards and delivery times, while accessibility via various communication channels is assessed in terms of response time and accessibility.
Very good — “The product packaging makes a very good impression and offers excellent protective properties. All relevant aspects have been met in an exemplary manner. ”
P2 - Scope of delivery & accessories
Category description
This is where it is determined whether a product is delivered complete, intact and immediately ready for use. The completeness, functionality of all parts, the quality of the instructions, internal safety and warning information, ergonomics and the accuracy of the accessories are checked. A complete, functional package avoids delays, increases customer satisfaction and reduces complaints or returns.
Logistik
Category description
The evaluation also includes shipping, which checks which regions the retailer delivers to, whether shipping is free of charge and is subject to conditions. It is also analysed whether the goods are shipped from a location in Germany/EU or from a non-EU country. Shipping packaging is assessed in terms of space optimization, protection and materials. When processing returns, it is crucial whether the return address is in Germany or the EU, as this influences logistical costs and the carbon footprint.
Very good — “The package is complete and in perfect condition. All required parts (instructions, accessories, if applicable) are included so that the product is immediately ready for use. Very convincing. ”
P3 - Material quality & visible safety
Category description
This test category assesses the materials used, their processing and compliance with visible safety requirements. Stability, surface quality, absence of harmful substances, material resistance and the legally required safety markings are tested. The aim is a product that is durable, robust and free from identifiable risks and thus meets the requirements of safety and quality in daily use.
Produktverpackung
Category description
To evaluate the original packaging (OVP), it is first checked whether the product is delivered in the usual commercial packaging that the customer would expect. A distinction is made between whether the OVP only serves as protection, as with electrical appliances, or is directly suitable for use, as with cleaning products. It is also examined whether the packaging offers sufficient protection against damage and environmental influences, including a drop test from a height of 1 meter. The materials and any odors in OVP are also assessed in terms of sustainability and environmental friendliness. The size of the package should be appropriate to avoid unnecessary empty spaces. Finally, it is checked whether the OVP is equipped with a sealing mechanism that prevents unnoticed opening and possible manipulation.
Very good — “The product makes a high-quality and reliable impression. No sharp edges, solid material quality and no identifiable sources of danger — convincing all round. ”
P4 - Ease of use & ergonomics
Category description
The focus here is on user-friendliness. Operating logic, handling, grip and holding comfort, adjustment options and points of view and access points are assessed. It is investigated how intuitively and fatigue-free a product can be used in different application situations. Ergonomic, clear operation increases safety, efficiency and satisfaction in use.
Inhalt & Lieferumfang
Category description
The evaluation of the scope of delivery checks whether all content promised according to the description is actually included. At the point of start-up, it is examined whether the product is immediately ready for use or whether the consumer must first make his own preparations. Bonus elements such as attached tools, assembly materials, batteries or discount vouchers that improve the user experience are also recorded. In addition, it is checked whether user manuals are available if the product is not intuitive to use and whether they are available in multiple languages or in digital form (e.g. via QR code).
Very good — “The operation is very intuitive and ergonomic — buttons, displays, settings are clearly structured and effortless. Hardly a cause for criticism. ”
P5 - Performance & efficiency
Kategoriebeschreibung
Diese Prüfkategorie analysiert, wie zuverlässig und ressourcenschonend ein Produkt seine Kernfunktionen erfüllt. Bewertet werden Funktionsumfang, Arbeitsgeschwindigkeit, Präzision, Stabilität der Leistung sowie das Verhältnis von Leistungsfähigkeit zu Energie-, Zeit- oder Materialaufwand. Ein leistungsstarkes und effizientes Produkt überzeugt im praktischen Einsatz und minimiert gleichzeitig Betriebskosten und Umweltbelastungen.
Produktqualität
Category description
The evaluation of the look, feel and workmanship ensures that the product is as described by the manufacturer, feels high-quality and is made from the advertised materials. In addition, the workmanship is checked for obvious defects such as scratches or dents. The next step is to examine whether the product has unpleasant odors, sharp edges or foreign substances that are not part of the product purpose. The practical test assesses whether the product is suitable for its intended use and is tested for resilience and stability, including specific stress tests. Finally, it is examined whether the product has quality marks, certifications or proofs of conformity.
Very good — “Outstanding performance and efficiency: The product performs its main task quickly and in a resource-saving manner, without significant weaknesses. ”
P6 - Durability & resistance to stress
Category description
This is where it is tested how well a product withstands typical everyday loads and how resistant it is to wear and tear. Material fatigue, joint stability, surface resistance and functionality after repeated use are assessed. A durable product ensures long-term reliability and contributes to sustainable use of resources.
Praxistest
Category description
In the practical test (not a long-term test), the product is rated according to the subjective perception and subjective findings of the tester (s). The classification is based on a star system of 1 to 5 stars.
Very good — “The product is extremely robust. Impact, friction or moisture cause hardly any wear — longevity is highly likely. ”
P7 - Product-specific features
Category description
This test category includes special features and functions that are specifically important for the respective product group. Individual performance features, additional functions, technical features and unique selling points that go beyond generic criteria are assessed. The aim is a realistic, fair and comparable assessment that reflects the specific benefits of a product for the consumer.
Preis-Leistungs-Verhältnis
Category description
External prices and customer reviews are used to determine the price/performance ratio. The price of the product is compared with the average prices of the first search page on Amazon in order to make a classification (deviations above or below the average price are represented by plus or minus symbols).
Good — “Very solid performance in terms of industry-specific parameters. Minimal deficiencies only in detailed areas (e.g. secondary function, scope of certificates). ”

Subjective user experience of the tester
Note on practical experience
The tester's subjective user experience — including previous experiences, expectations, and personal impressions during use. It reflects a personal, situational assessment and is not part of the DTI assessment. It does not replace objective examination or advice and does not establish any legal claims. The aim is to give consumers an assessment that is close to everyday life.
Breakdown sprays are only known to many by hearsay; assessments from workshops, retailers and the Internet sometimes differ significantly. Irrespective of the formal test objective, it is assessed whether such a spray — as a temporary solution, not as a permanent repair — will enable a safe journey to the nearest workshop.
Application: The illustrated instructions make it easy to use. Continuously pressing the trigger until it is completely emptied requires some force.
Driving impression: After driving off, a slight imbalance is noticeable, which is significantly offset by the recommended distribution route. After around 10 km, the measured tire pressure in the test was above the output pressure of the intact wheels.
Conclusion from a consumer perspective: For small tread holes, the spray offers a quick, easy emergency solution. Observe operating limits (not for cuts, sidewall/valve damage), comply with the speed limit and plan a trip to the workshop. A can in the trunk can help decisively in an emergency.
