Rovi X-3 model with attendant control and ELEVATION, and every feature you would expect from one of the best chairs on the market. Custom made in 2019 for a man 6' tall with the expectation he would be in the chair most of the day. The comfort level is excellent, from a super-comfortable cushion to a complete range of motion and "zero gravity." It was charged at over $25,400 and we paid $5,900 out of pocket for extra features. By the time it arrived, my husband had progressed more than expected and he does not need this chair. It was used 3 times, probably for 500 yards and is in as-new condition. Manual included-- there is no repair history because it is so new. We live near Norfolk VA and will drive up to 200 miles to help deliver but if you want to try out the chair you will have to come to our home.
