I received a Bog Death grip tripod for Christmas. At first the 360 degree rotating head would only rotate about 10 degrees, the adjustment knob makes no difference...it would kind of click when it rotated left or right. I loosened it up until the knob came off and then I got forceful with it and it would suddenly rotate 360 degrees like it should. As it rotates, its not smooth but feels almost like its catching on something inside. It seems really stiff and the adjustment knob makes no difference at all, it doesn't stop it from rotating. I don't care if the knob isn't working correctly, but if its supposed to rotate smoothly, I'd hate for it to get completely stuck after a few uses. My question is for those of you who have them, should it rotate smoothly? Thanks
