This is a light cover and keyboard to use with the iPad air, and it works seamlessly. I understand that people are concerned about extra weight, but it's important to keep in mind that any keyboard and case that can protect your device will add some weight.

I tested out two systems from Q-SEE. This one and the Q-See QT4760-8E4-1 Surveillance System (Black/White). They are at very different price points - this one currently at $2000 and the other currently at $700. Here, I will try to outline some of the differences between these systems. Even though they are at such different price points, hopefully this will help people sort out which type of system will be best for them.
Some key differences:
* To start, the QT718 is a much higher quality system with with HD cameras and full HD capacity. This make for much more precise image quality.
