The requirements are actually not high: round plate with a spherical cap under - done. In principle, yes, were it not for the material, the processing and the weight. This board is in complete plastic and consists of two glued parts - inside it is hollow. The material is hard plastic and thus one gets more times a loud creaking, what I would not have expected with my 80kg. But it holds - because I'm not worried.
The hard plastic is very smooth, so it is difficult to impossible to ascend with socks (two legs - one leg is of course because the center). The dome is made of hard plastic and therefore always requires a non-slip surface. It comes with a rather funny, about 15x15cm large "mat" is more reminiscent of a floor-impact sound. This mat does its work currently as a flower pot stand, to train I have a great yoga mat underneath.
The stand was me, as mentioned, too smooth. I have a Autofußmatte (Black stable rubber) cut out and glued it accurately. May look strange, but works great. The cap is quite high, therefore a large range of motion is possible, which I find very good.
I think the thing when it comes to price / performance mediocre. The good 20 euro were not worth my return, the Tuningvarinate works so perfectly now. Buy recommendation: goes like ...
