Good price on an item I needed

The prop was exactly what i ordered. much thicker than my repaired prop has been.

The online site is fairly easy to use

The product was in stock as advertised and received promptly; as compared to other that advertise but do have the item available at all.

Wonderful experience

Great

Great prices!

So far so good
