When I received this package, I thought there was no way these little stands workwork on my HP Spectre laptop. They looked to be too small to sufficiently keep it steady and slipping. Thre are no instructions on thte box, so it took me a few minutes to figure out how to seal to the bottom. I've been using them for several days now that I'm primarily working from home. Imagine my surprise these are pretty substantial and my laptop does not slip at all.They are very unobtrusive and honestly a good deal for such a low price. I'm quite happy with them. And, best of all, my wrists do not hurt from trying a weird angle. I would definitely recommond if you're looking for a reasonably priced laptop stand.
