Boldfit Pull Up Bar: Titangrip or Griplock?

Griplock has some bad reviews on amazon especially from those who purchased it from official website where as Titangrip has full 5 star reviews on amazon. Now at this point i find both these in terms of reviews ..shady and i don't really know which one to get.

No intention to pull my full 95kgs weight but between these two has anybody used either or what do you have at your home similar to this?
