So my first impression was very positive. The assembly is of course done in a matter of seconds. Overall, despite the handles make "plastic proportion" a very sophisticated look. In my opinion, the handle bends are themselves made of metal - could also be a very metal-like plastic. I had now not analyzed. Have you also tested on the same laminate. In my training stage it does not slip away. But it is of course also depends on how far they are apart and represents how fast / hard you perform the push-ups. And even if they should slip times, is simply glued rubber or similar non-slip down or otherwise placed in between - Keyword: Solution-oriented with minimum effort :-)
