ISOTRONIC
Insect repeller

The insect catcher from ISOTRONIC made a very good impression in our test. The product makes it possible to remove insects and other pests from the home without having to kill them or handle them yourself. This feature is particularly advantageous for people who are disgusted by insects or spiders.
The insect catcher can also be used to inspect insects more closely through the attached magnifying glass. This application can be of particular interest to children, as it allows them to get to know nature better and makes biology lessons much more tangible.

Advantages

✅Easy to use
✅Insects are not killed
✅Insects can be inspected
✅Family-run company

Disadvantages

❌Material consists of plastic

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.

Verpackung des Insektenfängers von ISOTRONIC
Packaging of the insect catcher from ISOTRONIC

The insect catcher from ISOTRONIC arrived for our test in a typical shipping box. The box was undamaged and easy to open by removing the adhesive strip. Inside the box was the insect catcher, which was wrapped in paper.
The packaging protects the product from scratches and dirt! In this case, the product was fully protected and the ultrasonic mite repellent was therefore in perfect condition.
The operating instructions, which could be read in 6 languages, were printed on the box to save resources.
The packaging of the insect catcher is completely recyclable.
The first impression of the insect catcher is very good, as neither the product nor the packaging used was damaged.

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 maximum score is 100 points

After unpacking, there was only the insect catcher on the kitchen table. This was wrapped in paper, which makes it easier to recycle.
The instruction manual was printed directly on the box, which saves resources.
Unfortunately, there was no email address or customer hotline printed directly on the box, which makes it difficult for customers to contact someone if they have any problems.
All in all, this is a very good way to send a product.

Unpacked insect catcher from ISOTRONIC

The insect catcher for makes a very good visual impression. It has rounded corners and has no manufacturing faults. It is made of plastic, but is very comfortable to hold. The product also impresses with its low weight and sturdy workmanship. The product cannot be bent and retains its shape.
The only indication of sustainability can be found in the packaging of the insect catcher, as care was taken not to use any plastic.

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.

CriterionRemarkScore achieved*

Possible applicationsMany possible uses – observe animals or catch animals100 points
Fun factorUsing it is a lot of fun after a short familiarisation phase100 points

Weighting: 30%
*The maximum score is 100 points

Catching insects with the ISOTRONIC insect catcher gave us a lot of pleasure during the test. Larger insects such as spiders or ladybirds can be caught very easily using the mechanism and released into the wild. With smaller insects such as small spiders, it can unfortunately happen that you accidentally injure the animal when closing the flap.
The use is self-explanatory and the magnifying glass is particularly practical if you want to take a closer look at the animals you catch in your home.
After the first few attempts at catching animals, they become increasingly easy to catch and you develop a great love of catching animals.
We are talking about a very great product that takes care not to kill all the unwanted guests in your home when driving them away.

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 ratioGood price-performance ratio92 points
Rating cut4.4 out of 5.0 on Amazon70 points
Total81 points
Weighting: 20%
*The maximum score is 100 points

On the Amazon platform, consumers have given the product an average rating of 4.4 stars. One common criticism is that the product does not capture all animals properly. Many customers like the fact that it is easy to use and that the magnifying glass is particularly suitable for small children. In our practical test, we were able to confirm that the size is a little oversized, but this is a major gripe. It is also very easy to use!

Prices of up to €38.90 are charged on the Internet for equivalent products. Very inexpensive products are available from as little as €11.49. With a price of € 19.95, the insect repeller from ISOTRONIC is therefore in the middle price segment in our test. The price ratio is very good for the quality and scope of services you get.
