Looks like the awesome Vortexes were too good to be true.
Yeah. I think theres something inside that is catching. I can't take it back I threw away the packaging!!! :@Its the friction between the two halfs! It has too much of it!!!
If there's too much friction between the two halves, I suggest you just unscrew it a little, loosen it up.
U can't. There is a flat screw holding it together!
Then how did you take it apart?
