It’s tiring having to hold a book or tablet. Instead of just reading, you have to apply effort to keep the page open or a tablet at a suitable viewing angle. These undoubtedly rob part of the joy or reading or viewing. And who uses a Laptop on the lap? You will end up with a hunchback and all sorts of problems from poor posture. That’s why a book/tablet/laptop stand makes sense.
Again there are plenty of choice on Taobao. It took me a while to find the right one. Most of the cheaper ones use a spring metal clip to keep the page open, but it makes me worry about damaging the book and it introduces a lot of difficulty to page flipping. You might end up tearing the page when trying to flip quickly.
I do like wooden or bamboo ones, and they’re surprisingly cheap (20+ Yuan), but they all come with the spring metal clip. In the end, i chose an Actto unit, a Korean brand. The design is very innovative. I’ll just let the images on the product box do the talking.
I also very much prefer the page restrainer mechanism that does not involve any spring action. Makes flipping pages easier.
All in all, i think this is a very practical item especially if you have kids who like to read, from a book or e-reader or tablet.
