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?

The design siphon from Bächlein arrived for our test in the typical shipping box. It was undamaged on arrival and could be opened without any tools .
The box contained all the relevant parts and the instructions for use in product packaging . The packaging method optimally protects the product from external influences. As a result, product protection was fully guaranteed and the design siphon was delivered in perfect condition. The packaging is also recyclable. In this respect, the product leaves a very good first impression. Neither the design siphon nor the packaging used was damaged.

The design siphon is ready for the practical test.

The tubetrap is made of high-quality 304 stainless steel and solid brass. The dip pipe, wall pipe and odor trap are made of solid brass. The rosette is made of rubber. The wall pipe is 330 mm long. The immersion pipe is 220 mm long. The materials used make a stable impression. For this reason, we expect a very long service life.

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.

We enjoyed working with the design siphon from Bächlein during the test. The siphon is made of very well-coated steel and looks solid.
In addition, the immersion pipe and the wall pipe were very long from the outset, so that after shortening (saw necessary) you can probably connect any washbasin really firmly and securely. The siphon can be opened at the bottom for cleaning with the key supplied. The look is elegant and the quality is excellent and it is easy to install. The gaskets seal well. Bächlein only uses high-quality, certified materials such as steel and silicone for its products. Since 2021, the company has been balancing its corporate ecological footprint to get an overview of how many greenhouse gas emissions they emit through their work at Bächlein. The breakdown makes it possible to identify potential for reducing emissions and to act accordingly. They attach great importance to continuously optimizing the resource cycle of their products. This sense of responsibility for the future is very remarkable.
Thanks to the high-quality material and simple packaging, the Design Siphon is also sustainable and saves resources.

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

*The maximum score is 100 points

On the Amazon platform, consumers rate the product with an average of 4.7 stars. Some customers often complain that the wall connection with the rubber sleeve does not fit. Many customers like the fact that the look is very modern. In our practical test, we were able to confirm that the look was good. We were unable to confirm in our test that the rubber sleeve did not fit.

Prices of up to €51 are charged on the Internet for equivalent products. Very inexpensive products are available from as little as €25 . The Design Siphon from Bächlein is therefore currently in the middle price segment with a price of € 39.95. For the quality and performance received, the price-performanceratio isvery good.
