I got these stands for my laptop and iPad. I got these to help with my daughter’s posture while she is doing homework on her laptop or gaming on her iPad. I love the clean, minimal look of acrylic and these stands are very aesthetically pleasing! They came with little tools to loosen or tighten the bolts. They extend nicely and give good height. I didn’t have to worry about my kindle falling off the stand even with it fully extended. At first my laptop was a little too heavy and the stand couldn’t hold it up, so I used the tools to tighten and it’s very sturdy now. This was a great purchase and great quality. I got the two pack bc it was a better deal!!
