quick deliver but paint product was dented

The cv boots I purchased fit perfectly and seemed to be very good quality. Shipping was quick also, I received them two days after ordering.

would have liked an estimated delivery date upon ordering so I knew when to look for it. Also $13 shipping for a small light cap seems excessive, I paid $20 for a $7 light cap.

My only comment is the shipping costs are excessive!

would just like better description of item that is being purchased

Excelent
