Elevators came earlier than expected. They were pretty easy to install and worked as expected, although the draw pressure was a little less than I expected. To my delight, the salesman reached out to ensure the elevators were satisfactory. This interaction was very rewarding and I am impressed with the willingness of the sellers to endorse their product. Overall I am very happy with the purchase and even more so with the service. Make sure you get the right ones for your specs and I think you'll be happy. If there is a problem, the customer service is top notch. what's not to like?
