I live in a rural, off-grid/solar power-only area where power can be an issue. I purchased this keyboard/tablet holder to extend my "computing" time significantly, and it does the job perfectly. Although the keyboard is a bit small for my large hands, the keys are spaced out enough that I can easily write or code even when my laptop battery is almost dead. This keyboard also makes for a smaller device to carry to cafes and meetings. Instead of lugging around my laptop, I can pull out my tablet with this keyboard (and a separately purchased Bluetooth mouse) and get to work. It's one of the best purchases I've made on Amazon.
