When I created the RV Flex Repair product line, I wanted it to be hassle free and last the life of your RV. I feel we've accomplished this and stand behind our products 100%. If for any reason your product has an issue, I will replace it or refund it over the life of your RV. Even if something strange happens like a branch goes through your roof, let me know and I'll send you out free product to fix it. I don't know of anyone else who stands behind their products like this.
