Query: WARNING STAY AWAY

This rail is Pure Trash it wobbles, moves all over the place when you try to jib it. I could never get it level and it had a nasty lip where the 3 rail pieces joined that you could feel every time you tried to slide or grind.. complete CRAP if you want to waste your money please just send to my pay pal account I Need it. STAY AWAY FROM THIS RAIL.. AGAIN STAY AWAY
