The Asus ZenFone 2 Laser(ZE550KL) looks similar to the Asus ZenFone 2(Review| Pictures). Both handsets are the same size and shape, and Asus retains its distinctive concentric-circles pattern on the chin of the device. It’s near-impossible to tell the difference between the two phones at the front.The sides remain free of any buttons or slots, and the bottom has the Micro-USB port. The power button and 3.5mm port are at the top of the device. Touch gestures within the user interface allow you to wake the device with a double tap and launch certain apps, so you won’t really need the power key for much apart from powering on and off the device.Like the ZenFone 2, the volume rocker of the ZenFone 2 Laser is at the back of the device, just under the camera. Although it takes some getting used to, we eventually got comfortable with the positioning and it’s a convenient place to put the volume controls. We were also satisfied with the display, which at 720x1280 pixels is suitably sharp for a budget device. Colours and brightness are adequate as well.You can leave it to Asus to be even more confusing than you expected, with multiple models within the ZE550KL sub-model of the ZenFone 2 Laser. The device we have for review has a 5.5-inch 720p screen, with a Qualcomm Snapdragon 410 SoC and 2GB RAM on board, while there is also a Snapdragon 615-powered option with 3GB RAM.
