This review is going to cover something a bit different than the usual fare at Bigbruin.com... A virtual keyboard that is created by projecting a laser on to your work surface and that connects to your computer/phone/tablet via Bluetooth. Even though I have seen these around for several years, the idea still seems pretty out there to me, and as such I have always wondered how these things really performed.



Gearbest.com sent over the Atongm (don't ask me how to pronounce that) branded Bluetooth laser projection virtual keyboard shown in the promotional image above. It is a compact device, and honestly if someone were to hand one to you, it might be difficult to guess what it was. We'll go through the basics of the device soon enough, but first let's take a look at the features and specifications found on the Gearbest.com product page...
