This is a very dangerous item to open even slowly, it pop so quit it push me over plus broke my glasses and I jutted my tooth. It took 2- 6ft men to fold it back up and it will never pack up as small as the factory sent it even the belt holder won’t go back on . When I watch the video I thought it would be easy for me to put up and down by myself. The force of the opening it is unbelievable. I been looking at this for a year and was so disappointed when it came. Would fit on balcony but landlord said unsafe unit for this purpose.
