Try it, take a laser pointer and shine it on a black surface, and then move it over on a white surface. Lasers look different on black or white surfaces. When you lightly touch the silver nub, the keyboard instantly turns on or off. The CL850 sports a built-in battery and a neat touch-sensitive silver nub on the top that looks like a button, but doesn’t depress like one. When I turned off the lights, the keyboard looked much better, even on the granite surface. Surprisingly, it performed well, accurately responding to my key presses and not misfiring. My first test with the CL850 was to turn it on in an unforgiving environment. The lack of weight, however, tends to give it a somewhat cheap feel. Lightly shaking the device, I could hear slight rattling - overall not too bad though. The device also fails the “rattle” test, but not by much. With the USB cable plugged in, the slightest nudge on the cable moves the device, moving the keyboard display dramatically.
The CL850 is really small and very light. So, here we go.ĭon’t let the box fool you. I felt compelled to write this review because every other review I saw had awful low-res out of focus photos and didn’t show the product in enough detail. I decided on the Celluon LaserKey CL850 because it is the latest laser virtual keyboard and it supports a USB connection, unlike the CL-800BT which only supports bluetooth.
