I’ve been selling the rev HD seals for approximately four years now. Almost every customer that I show them to still buy them. I feel they are the best seal on the market. The no questions asked warranty and the support of Rev HD is far above any other supplier that I deal with. You can sell or use this product with confidence knowing that it will do the job it was designed to do with little to no failure and if by chance something goes wrong the company stands behind their product 100%. I feel if a customer is not utilizing this seal then they are missing out on a simple but great product. Brian is very knowledgeable and is a great asset when making sales calls and trying to introduce the products to potential customers and buyers
