The things work just as it says in the description. They are attached with a self-adhesive tape so they can be easily removed. The velcro straps holding it are a bit small for my taste but seem to hold up well. And it's really good that my MacBook Air sits upright and allows air to circulate. And because they're attached, I can move the laptop around without fiddling with the stand. They are not as durable as a real laptop stand. but they are small enough that you can use them as a prop for your cell phone.
