Anyone that doesn’t have a 5 star review on these, simply aren’t using them correctly. Lock the lever back until you hear a click and they fit bars perfectly fine and then when you lock it down, they fit very snug.
Great product but these guys

You know that feeling when you eat an aggressive California burrito and have a couple of beers with the boys, then immediately lay down in bed snuggled up with the AC down to 64, and take a solid nap? Don't ask me how; but, this mimics that.

Collars are sturdy, metal, hold great, and look sexy. Always remember, If you look good, you feel good, and if you feel good, you play good.

These puppies will taunt you and have you slapping on another plate.

Excellent product! - Sean
