"We are very happy with RayTalk. The product quality is better and your pricing is comparable to the suppliers that we used previously. Usually we receive shipments from you 2-3 weeks earlier than our previous suppliers, which is very helpful.  I also love that you are able to mark the products with our part number - this makes it much easier for our warehouse to receive and sort the product."
