As you refer to the warping cue experience as "it", I assume you had one cue that warped. Even if you had more than one, extrapolating to suggest that all Joss cues lack workmanship and quality materials is not logical.
I doubt that any cue maker in history has achieved satisfaction on every cue they or their employees built. Until I start seeing a multitude of complaints I'll go along with the folks who express their appreciation for Joss cues...and I'm among them.
I wonder if he was the original owner of the cue. If so and it warped within two months was Joss contacted and then they refused to remedy the situation. To me that scenario sounds suspicious, most all reputable cue makers in America would stand behind their product for a minimum of 12 months and some for far longer..
