Ru9 understands that, just 20-30 minutes at the store can't give you the full feeling of a product that will stick with you for many years. Therefore, Ru9's 100-night trial will allow customers to try and experience Ru9's products right in their bedroom. And if you don't feel completely satisfied for any reason, you can return the product and receive a full refund, equal to the amount you paid minus the return fee.
