This product is very cheaply made! One of the main structs bent the 1st time I tried to open it. Wayfair, however, were great. they are replacing the item & should be here in less than 2 weeks.
If the manufacturer had included decent instructions with a caution that the struts must first be partly opened by hand before using the turning mechanism, the damage probably wouldn't have occurred. I'll have to wait to see how the replacement one holds up.
