These clips make it extremely easy to attach stage skirting to our portable stage. The velcro has lasted a solid year, the only reason I rated a 4 star is because over time if you're constantly purloin your portable units in and out of rooms...they tend to bend and fall off a little easier. But for the price, it works out well for us. I haven't found anything better at this point. Stage Drop has delivered us some good products, particularly our stage.
