I have to say , this is one awesome deal. I got the to be able to work in my shop . It was very easy to assemble and little difficult to program and adjust the height . But once is calibrated it works perfect . Come with a digital display with a USB port . Only issue when you press the down button you need can hold to long it freezes. But when you select a height it goes to it .(used a level and measuring tape and it close to a 18 of inch.
