Rusty asked why not just get Le Pro instead of the knock-off, ThePro?
Cue Components explained that the Le Pro company (Tweeten) is stuck-up and it hasn't done anything since Grandpa Le Pro invented Le Pro. Le Pro's $1.50 price is too much versus ThePro's $1. If you can tell the difference in play between a Le Pro (one that's good, anyway) and ThePro? Cue Components will eat your returned ThePro with a glass of milk.
From Cue Components:
Tweeten Fibre Company (manufacturers of the LePro Cue Tip) is a very difficult company to work with, sort of stuck up and for no good reason. They believe they have a niche market with a few products. Quite frankly, they have never done anything since "grandpa" invented their company & products.
With Tweeten's quest for arrogance, we decided to manufacture a competing product and sell them for a much more realistic price! Introducing, our all new ThePro™ Cue Tips. If you can tell the difference in play (when you get a good LePro), send them back and we'll eat them with a glass of milk!
