I found exactly the product I needed on their website. I was too fast with my fingers, though, so I ordered the incorrect size. After a quick e-mail to customer service, I received a PHONE CALL and they were able to correct my mistake and ship the correct product.
I would DEFINITELY buy from 4rails.com again.
