ISOTRONIC
Ultrasonic mite repellent

The ultrasonic mite protection from ISOTRONIC made a good impression in our test. As well as being easy to install in the socket, it impresses with its odourless and noiseless operation. In addition to repelling pests such as dust mites or bed bugs, the ultrasonic mite repeller also guarantees no acoustic disturbance to sleep, as the ultrasonic technology transmits several sound waves that are inaudible to humans and are intended to disturb the pests. In addition, the technology used does not require the use of additional chemicals, which makes it safe for animals and people in the household.

Advantages

✅No use of chemicals
✅Silent
✅Easy installation/use
✅Family-run company

Disadvantages

Green LED can be unfamiliar when sleeping (especially if you have a very dark bedroom)

The test

General information

We have looked at and tested the product in detail in a practical test. In the following, we take a closer look at the features and impressions. The product is subjected to our test procedure from the packaging, materials and quality to the range of functions and handling.
To give you a quick overview, we work with a points system. The maximum possible number of points per area is 100 points. The final overall score is calculated from the average of all tested features, taking into account the respective weightings.

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 Ultraschallmilbenschutzes von ISOTRONIC
Packaging of the ultrasonic mite protection from ISOTRONIC

The ultrasonic mite protector from ISOTRONIC arrived for our test in a typical shipping box. The box was undamaged and easy to open by removing the adhesive strip. The box contained the ultrasonic mite repellent, which was wrapped in paper, as well as detailed operating instructions in 6 languages. 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 packaging of the ultrasonic mite protector is completely recyclable.
The first impression of the ultrasonic mite protector 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 were two things on the kitchen table. Firstly, the ultrasonic mite protector, which can simply be plugged into a socket, and an instruction manual, which is supplied to the customer as a reference book.
Instructions for using the product can be found on the packaging and in the operating instructions. The contact information can be found on the box and the e-mail address can be obtained by scanning a QR code.
All in all, this is a very good way to send a product.

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?

Ultraschallmilbenschutz von ISOTRONIC
Ultrasonic mite protection from ISOTRONIC

The ultrasonic mite protector makes a very good visual impression. It has rounded corners and has no manufacturing defects. The casing of the ultrasonic mite guard is made of plastic, which is very comfortable to hold. The product also impresses with its low weight and sturdy workmanship. The product cannot be bent and remains dimensionally stable.
Information on sustainability can only be found for the packaging of the ultrasonic mite repellent, as care was taken not to use any plastic. However, the manufacturer gives a three-year guarantee on the product.

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.

CriterionRemarkPoints achieved*

Weighting: 30%
*The maximum score is 100 points

We enjoyed using the ISOTRONIC brand ultrasonic mite repellent during the test. You can simply plug the ultrasonic mite protector into a socket to put it into operation. No further settings are required for commissioning.
As we installed the ultrasonic mite protector in the bedroom, we also tested whether the product does not emit any audible noises for humans, as stated. We can fully confirm this, as our tester was unable to hear any aud ible noise from the product despite having good hearing.
The effectiveness of the ultrasonic mite repellent has been confirmed by the University of Milan. The manufacturer also explicitly points this out in the instructions.
However, the LED light was very bright for the tester, as he was only used to sleeping in dark rooms. After several nights, however, these initial difficulties subsided .
We are talking about a very great product here.

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.

CriterionRemarkPoints achieved*
Price / performance ratioVery good price-performance ratio95 points
Rating cut3.3 out of 5.0 on Amazon15 points
Total55 points
Weighting: 20%
*The maximum score is 100 points

On the Amazon platform, consumers have given the product an average rating of 3.3 stars. They often criticise the fact that the devices break after just a few weeks. Many customers like the fact that it is easy to install. In our practical test, we were able to confirm that it is very easy to install, but we cannot confirm that the product breaks after just a few weeks. If it were to break, customers would also have the option of returning the product and making use of the three-year guarantee!

Prices of up to €149.99 are charged on the Internet for equivalent products. Very inexpensive products are available from as little as €19.69. With a price of € 25.95, the ultrasonic mite repellent from ISOTRONIC is therefore in the lower price segment in our test. The price ratio is very good for the quality and scope of services you get.
