Unlike other retail operations, we do not hide behind the cloak of an LLC/corporation or the anonymity of the internet. Our founder, Jeff Kenney, personally stands behind each and every sale. We have a history of over 20-years of 99+% perfect feedback established online over tens of thousands of transactions to show for it. And after an order is received, these manufacturers go beyond their duty in standing behind their manufactured product, with us helping to facilitate all warranty claims as well for a hassle-free experience. Problems are taken care of quickly and cost-free. If you are left questioning us as your vendor, please inquire for more information, as we are always willing to share so that you feel comfortable.
