Was exactly what I needed. Easy installation, and is working perfectly ever since.
Good description and rapid handling and shipping.

Used and abused, and still working fine.
Larry - 04/17/2022


Whenever I messed up my pen I went straight to the internet and looked for it. Then etrailer came up with exactly what I needed. Is that dimensions and information. So it was very easy very simple and within 4 days I had my product. I really do appreciate the quick service and availability of the trailer being on the internet.


The pin is good and does its job. But the customer service is beyond excellent. Originally my order was out of stock, Michelle contacted me and we decided to go ahead with the order. She contacted me when it came in and was shipped. Unfortunately I moved in the meantime and the pin was returned, I talked to Michelle and she had it resent No problem. Thank you Michelle.

Perfect in every way. You guys are great
