Unfortunately, I was not satisfied.
The construction is sturdy and of good quality.

However, it has specific drawbacks
a) it is very narrow. It is not 39 cm long; I measure it at close to 35.
b) it is very low, with a maximum height of 8 cm
c) it slips if, for example, the surface is tile/marble.

It is a good purchase if someone uses it only while standing upright during work.
If you are reclining in the chair, for gaming or multimedia, its small size/height limits you a lot

It is perfectly ergonomically designed and very sturdy construction. I am very satisfied with the product

Sturdy construction. It is indeed low and another downside is that it doesn't lock and when shaking the legs it moves back and forth.

Very good and quality product. It's not worth spending 10 euros to buy a plastic one that you will throw away in 3 months. Also, what they say about it being a bit low is true, but it doesn't create any problems in a normal office.

Very good quality construction and stable. The only negative is its height, it is quite low and you need to put something underneath to raise it a few centimeters. I believe it should be twice as tall.

The only positive thing is that it is metallic and won't easily break. Initially, it is very low, below 10 cm in height. The handle that adjusts the call is very soft without any resistance, so with a little movement on the foot, it turns. Also, it is not stable, it has two rubber bands on both ends that are supposed to "stick" to the ground. Not to mention that if you push it and hold resistance, the rubber bands can easily come off.

The only positive thing is that it is metallic and will not easily break. Otherwise, everything is wrong. Initially, it is very low, less than 10 cm in height. The dial that adjusts the call is very soft without any resistance, so with a little movement in the foot, it turns. Also, it is not stable, it has two rubber bands at the two ends that are supposed to "stick" to the ground. If the floor is not freshly cleaned, it does not stand at all. Not to mention that if you push it and hold resistance, the rubber bands can easily come off.

Edit: If you have the same problem of it easily turning, I solved it by putting a little toothpaste on the lines it turns.

The quality is so good that it makes me wonder what more I should expect from a more expensive alternative. It doesn't seem like it will wear out over time and the color, although serious (suitable for an office), I would describe as unique. It has protective pads for the floor in the front and back, while the material of the surface that the feet rest on gives a relieving sensation. If I have one negative thing to say, it is that it is somewhat low, but I can't say that other footrests are much higher. You can't lock the footrest in a certain position, but the friction of the moving parts is enough to hold the desired tilt. Here I should note that I just received it, so the assessment of the quality is entirely based on my first contact with the footrest, although I don't think my opinion will change in the future.

I bought the Eureka as a replacement for a previous footrest, which, although not cheap, broke. I chose it for its steel/rubber materials and so far I am completely satisfied. It is not huge, it takes as many convenient angles as needed, and it appears to be very durable...

So-so.. It has good construction and is quite sturdy. Personally, I find it somewhat "low" for my taste and for the height of my desk and chair, as even at the lowest point when I lower the chair seat, it still remains quite low for my legs, resulting in more weight distribution on my thighs. Construction-wise, I would prefer the recline to be a bit firmer because whenever I shift my weight on the foot, it moves. It should be noted that this is not the Eureka model with the lock. It has a good grip both on the plate that the feet rest on and on the points that touch the floor, so there is no slipping.

It has helped me a lot. I spend several hours on the computer and I can say after 3 weeks of use that the pain in my legs when they "hang" has disappeared. Highly recommended
