I've been thinking about getting one of these for a while. I play a lot of video games on PC and have often thought it would be useful to have a second screen for when I need to look up guides or even when I want to watch a football match at the same time. I don't have the space or money to get a second monitor but with this arm attached to my desk I can use my iPad for everything I'd use a second screen for.
I am very impressed with this product. It didn't come in the flashiest packaging so I'd keep that in mind if you're buying one as a gift, but if you're buying for yourself you'll probably just throw the box away anyway so it doesn't matter. The product itself is very strong and feels well made. It holds my iPad extremely well and, as long as you attach it to something solid, doesn't move when in use. I would say though that it takes a bit of force to bend this into the position you want so an older person might struggle to position this properly.
Overall I am very happy with this and am happy to recommend it to others.
