I've been using one and loved it until a couple weeks ago I left on my pocket and lost somewhere between the bar and home. Ordered another one. Holds the chalk tight have never had it fallout which was my concern when I ordered it.
I know they are a production cue and not custom, but they are american made and I love their shafts. Everyone I know has had great luck with their customer service. Just curious if anyone has hit with them yet. Seem like a decent price.
