What Do People Say About Our Company?

Ever since our kickstarter launch in 2012 I’ve been working with Randy and his team and they’ve done a fantastic job of producing our product. It’s been several production runs each year, and couldn’t be more pleased with every aspect of the product. Randy’s been fantastic to work with, very capable and trustworthy, and I have no problem recommending him to anyone looking to get a product made in China.

Randy Williams and his team at World Sino Sales & Support, Ltd were a great help to Rust-Oleum as we undertook our first-ever Asian Sourcing initiatives. Their knowledge of factories and their areas of expertise, different locales, and business cultures helped open a lot of doors for Rust-Oleum. The end result was a strong contribution to Rust-Oleum’s bottom line as we realized new costs savings across a number of product initiatives.
Mark Boufford
Senior Brand Manager of Rust-Oleum Corp
I’ve done three kickstarters and Randy has done all the products for them. If there are manufacturing problems, he deals with them so you don’t have to. It makes the whole notion of having things manufactured in China a lot less risky and a lot easier from this end. I can definitely say that my business wouldn’t be where it is today if I had not connected with someone like Randy. So I would definitely recommend anyone who’s thinking of manufacturing in China to go with Sino Sales.
