I bought this for my 90 year old father who has a Pride Celebrity XL scooter. My husband put it on. The screws on the arm rest were very tight but once he got the screws off and with the proper tools the canopy went on which provided my father with shade and added visibility for drivers to see him. It comes off easy if he wants the sun to shine on him and very easy to put back on. The height of the canopy is the right height to get in and out of the scooter. Good product and my father is happy with his canopy.
