The instructions to connect the Keyboard was very basic and easy to follow. Setup took a minute. The different color backlights are a fun plus as well. I haven’t experienced any delays and the battery life is really great. It’s also really great the the charge time is very quick. The only down side, is the care is very tight and the off and on volume up and down buttons are very stiff and hard to push. Hopefully they will loosen over time. Other then that tis was a great buy.
