Is wp_is_mobile() effective?

I’m going to test the user agent to load a mobile template instead of the desktop theme.

There are many mobile detection scripts out there.

• Does wp_is_mobile() function work well?
• What is your experience in comparison with other classes like e.g. mobiledetect.net?

Yes it works well. It’s a very simple function but never found a mobile device not recognized by it. It recognize the 90%+ of mobile devices. Main difference from mobiledetect.net is that doesn’t differe from phone and tablets.
