Yes have had it for a couple of years now. Best tool in my garage and so glad I picket it up. I have a post tensioned slab so maxjax or a two post was not an inexpensive or easy option. I looked at four post and it was going to take up too much room and cost a lot more once I through in slider jacks and the runners keep you from getting close to your work.
I like that I can keep it stored under my car and it is out of the way and it goes up plenty high for the work I do. I actually found the first lock is the perfect height for doing brake work and sitting comfortably in my rolling chair! At full height its still a bit of a squeeze getting under the car but I can actually do it in my rolling chair so it keeps it comfortable. I did get some race ramps because two of my cars were too low to clear the lift without handing up on it.
Middle access is probably the biggest issue people have. You have to answer that question for yourself. How much will you do right in the center of the car. I was still able to work on the shift linkage so it is not that bad. Here are a few pics. Very happy overall.
