Any have these legs?

Just wondering if anyone has tried this landing gear? They look very light and would provide a stable nice base. Any thoughts?

I bought them, but have to say that requieres a great work for setting the compass in the correct angle... too sensible to changes. They works great but you have to be a surgery hand moves with compass for avoiding drift while flying. That said, they worked great. Note: they sell only the ending parts but you have to get carbon fiber or 6mmm aluminiun tubes (these are mines white painted).
