Customer service. Stacey was very professional and helpful and a product were great more than I expected.



by:

Overall worked with some modifications. Pictures show different brackets than what came in package. Actual brackets are not as sturdy and missing middle one. Had to order different brackets because these would bend when ramp was opened. Not sure why the picture shows 3 when it only ships with 2. Must be an update to save some money. Wish I would have know before purchasing. Once installed, springs did their job and trailer ramp is easy to open and close.
