My Lubix Guhong is not the same as what it was new out of the box(16-17 days back), it is suffering from a decent amount of friction(i solve it at least 8 hours daily so the silicone might have finished or something), so what do i do? If i loosen it, it explodes, if i tighten to the original amount, it locks a lot. I dont have anything except vaseline at home. Should i arrange a silicone spray? Or am i the only person who is facing this problem with lubix guhong?
