I just got mine yesterday, mounted on INCRA 24x32 table with PC690 router. It is very well made unit and lift is silky smooth. Mayor problem for this type of device is driving screw thread backlash (up/down slack). This unit does not have it. Jessem Rout-R-Lift II leveling screws pattern does not fit my INCRA pattern, so the set screws that comes with the unit are leveling against MDF (that is bad). I just purchased for $4.95 as Lowes 1/8" x 3/4" x 3' flat aluminum stock so I can cut it up and use it as base for leveling screws. This is simple. The mayor problem for me ( I was mold designer and mold maker for over 30 years, so I am use to precision) is that Phenolic plate is bowed-up by as much as .008in. I am working now with Jessem to see what can be done about it. I will post the follow up for this issue. There is a lot of talk on the blogs about poor customer service at Jessem. In my case I could not have more pleasant expearience, they were great. Jessem just raised price to $169.99 but it is still great for what you are getting.
