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.

CLIDOR
Storage jars

In our test, the storage jars from Clidor made a very good impression. The storage jars are made of robust glass, which is 3 mm thick. The vacuum lid made of bamboo ensures safe storage of food as it does not allow air to pass through. Unfortunately, the bamboo lid has to be cleaned by hand, but the jars can easily be cleaned in the dishwasher. The jars can be clearly labelled using the stickers and pen provided. Unfortunately, it is not possible to store liquids safely in the storage jars as the jars are only closed with a rubber band and not a screw cap.

Advantages

✅ Robust glass thanks to 3 mm thickness
✅ Safe storage thanks to vacuum lid
✅ Easy cleaning in the dishwasher
✅ Labelling with included stickers and pen

Disadvantages

❌ Not suitable for liquids as the lid does not have a screw cap

The first impression

The packaging and labelling

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 ensured.

*The maximum score is 100 points

The Clidor brand storage jars arrived in the typical Amazon box. The box was undamaged. Inside was the box containing the storage jars. It was easy to open without any tools. The box was also beautifully labelled with the product description. There was also foam inside the box to protect the jars. In this case, the product was fully protected and the storage jars were therefore in perfect condition.
The packaging of the storage jars is partially recyclable. Unfortunately, the foam is not recyclable, but the cardboard is.

After unpacking

Package contents and instructions

ℹ️ Most people’s first impression after unpacking is immediately memorable. Are the contents of the pack complete and does the manufacturer make it as easy as possible for me to use the product straight away?

The box contained the set of 6 jars. It also came with 6 stickers and a chalk pen for labelling the storage jars. In addition, a card was supplied with the jars containing the instructions for use, contact information and even the history of the storage jars. Before using the storage jars, you should rinse them out once. Afterwards, however, you can use them straight away. In general, the product makes an extremely high-quality impression.

The first time in your hand

Product processing and appearance

ℹ️ Before we start the practical test, we take a close look at the product processing. How high quality are the materials used? Is the look and feel satisfactory?

*The maximum score is 100 points

The mix of the glass and the natural bamboo lid gives a very nice visual appearance. The two components are also very well made and give a stable impression. The 3 mm thick glass in particular looks very sturdy and can withstand the odd fall. Unfortunately, the rubber seal is not entirely durable, but overall the storage jars make a very high-quality impression, meaning that they will last a very long time.

This is what our practical test showed

Does the manufacturer keep its advertising promises?

ℹ️ Our practical test is the most relevant and therefore the most important. 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

Every time you use the storage jars, you notice the extremely high quality of the storage jars. You also notice when you open the lid that it is very tight. Thanks to the simple design of the jars with the natural bamboo lid, the storage jars fit into any kitchen or pantry. The storage jars also protect against air, moisture and moths, although the jars are not suitable for storing liquids as there is no screw cap, only a rubber seal. The storage jars can be stacked on top of each other and also individually labelled using the stickers and pen provided. The three different jar sizes also help to store them perfectly in the kitchen. Overall, the storage jars were more than convincing in all areas.

Price/performance ratio

and ratings from consumers

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

CriterionRemarkScore achieved*
Price / performance ratioAverage price, very good performance95 points
Rating cut5.0 out of 5.0 on Amazon100 points

*The maximum score is 100 points

On the Amazon platform, consumers have given the product an average rating of 5.0 stars. The only criticism is that the storage jars are not suitable for liquids. Many customers like the high quality. In our practical test, we were able to confirm that the quality was extremely good.

Prices of up to €49 are charged on the Internet for equivalent products. Very inexpensive products are available from as little as €34. With a price of €39.99, Clidor storage jars are currently in the middle price segment. The price ratio is very good for the quality and range of services you get.
