Previously I had used plastic which, due to the the fact that they are in one piece, of course, come along more robust. Advantage of this part for me: - Size of the support surface: ideal - Edge quite well restrains accidental slipping - Height: Top and better than previously known, more relaxed to use, since it remains a little "move" under the part.
I'm curious to see how does the mechanics of the feet during prolonged use, so far I am satisfied. And for all the critics when it comes to robustness of feet etc .: What do you expect? Spend little money but ?? eternally indestructible I think at sensible (!) Use OK also in the longer term.
