Es sind halt Keen;-) Overall good. I bought this keyboard to find an improvement on my previous keyboards and instead discovered the true meaning of love. I know on the description it states you can sit on the bench however we do not sit on it as I do not think it would be sturdy enough to sustain more than 120lbs. Follow the instruction every time I use it, and my weight is way lighter than the limits. Other than that they are cute and do what you would imagine they do by looking at the photo. No arch support So I got her the camera. My Son loved them and seemed very comfortable for him but if wearing everyday they won’t last long at all which is why I gave it 3 stars but they’re a netting type material so makes sense. And, not just for kids.
