The unit is easy to assemble, but it takes a few minutes to get all the bolts tightened. It is very sturdy except for the foot hold which has a slight wobble even when securely tightened. Maybe it's supposed to have a wobble. The customer service for this company is also very good to answer questions and be of help. Their rep emailed me pics to show the slant that the correctly assembled unit should have. The length is easy to adjust. There is a strap that allows the unit to slant only as far as you wish it to go. This is a good feature, but I might change the strap/buckle to a chain to make changing the setting quicker. Overall, this is a great unit with good features, like folding to put away/having handles/holding 275 lb person, etc.). It was a terrific value. I got a lot for the money.
