@kid168 We really never answered your question so here's my take on it . I also have the Du-Bro one and I just let it sit on my desk
with a prop on it for looks . It does a great job . I can't see no difference using it verses the glass .
I find it easier with the glass but that's just me .
I always check my new OEM props for balance before I will use them . I have only found a few that where a little off .
You can spend the money and get a store bought one or do as I did in the post above . I have never seen any difference
and have checked them against each other . JMO...Here's my store bought. could have used that money for another set of prop's
