The first impression

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 Zenakio carpenter’s square is carefully packaged. The sturdy cardboard box offers sufficient protection during transportation. Although unnecessary packaging waste has been avoided, the use of plastic film could possibly be a point of criticism for some consumers. The set contains a combination square with spirit level, shaft and scriber as well as a carpenter’s square. A multilingual instruction manual with tutorial videos is also included.

Carpenter’s square
Joiner’s angle and combination angle

The brackets are characterized by an attractive and simple design. The joiner’s angle is made of robust aluminum, while the combination angle is made of stainless steel. The workmanship is predominantly very good. There are no marks or scratches, although there are a few sharp transitions. The product appears stable and makes a robust impression. Although no explicit information is given on the sustainability of the product, the high-quality workmanship suggests a certain longevity.

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.

*The maximum score is 100 points

The measurements were reliable and accurate, which is particularly important for demanding timber construction projects. The angles proved to be very easy to read . The markings are clear and unambiguous, minimizing measurement errors. The printed conversion table makes work even easier and enables a versatile measuring system. With a total of 12 functions , the set offers a wide range of possible applications and makes it a real all-rounder for DIY enthusiasts. The two angles enable a wide variety of measurements to be taken on wooden or metal parts and can be used as a routing template or marking tool. The ergonomics of the angles are pleasant and allow comfortable handling. The quick application saves time and makes work on the construction site easier . However, we have found that the shaft of the combination angle can be moved with some effort despite the locking screw, which can affect accuracy in certain situations. A more stable fixing of the shaft would be desirable here.

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.

CriterionRemarkScore achieved*
Price / performance ratioVery good100 points
Rating cut4.4 out of 5.0 on Amazon70 points
Total85 points
Weighting: 15%
*The maximum score is 100 points

On the Amazon platform, consumers rate the product with an average of 4.4 stars. The accuracy and quality of the angles are rated very positively. However, some customers complain that the combination angle is not right-angled and that the corners are sharp. In our practical test, we confirmed the precision of the angles and found some minor weaknesses in the workmanship, but these did not significantly affect the overall impression.

Prices of up to €35 are charged on the internet for equivalent products. Very inexpensive products are available from as little as €23 . The Zenakio carpenter’s square is therefore currently in the lower price segment with a price of €14.99. For the quality and performance received, the price-performance ratio is very good.
