There are three aspects to the reason I unfortunately could only rate my satisfaction at a three. Number one would relate to the build of the framework of the chair. They did an excellent job on the framework, it’s very solid and comfortable. Number two would relate to being able to fold and unfold the chair and put it in the trunk of my car. It folds and unfolded very smoothly and it is heavy but I was able to use a little leverage to make it pretty simple to put it in the trunk of my car. Number three relates to actually using and controlling the chair. Unfortunately this is the TOTAL REASON FOR MY DISSATISFACTION, and low score. The controller performance is totally destroyed by the way the controller is programmed. Instead of giving the customer full control of operation so you can move smoothly, they have restricted your ability to control the chair by limiting your choices. If you are going straight and even slightly move the controller to one side or the other the controller anticipates the fact that you may be turning and it automatically slows your speed greatly. So if the surface you are on leans even slightly one way or the other, you may be intending to go straight but the chair may drift a little because the surface is not perfectly flat and when you move the controller slightly left or right of center in the forward position to compensate for the drift, the chair automatically assumes you are making a turn and it slows down instead of letting you be in total control. Most people that buy this chair are adults. Unfortunately they apparently don’t think their customers are competent enough to operate the chair safely, even though the chair has five speeds to choose from and customers should be able to set the speed at a level they are comfortable with. I must say that the customer service department is very nice and quick to respond to problems, but unfortunately can’t solve this problem until management quits over thinking safety and maybe liability. I hope they choose to give the customer the ability to control the chair smoothly in the future, the satisfaction, rating level of customers will increase greatly when they quit restricting the performance of their products.
