From what I can see of the construction, it's a printed case. Then there are four tiny buttons on top, which would make it hard to get the right one when you are framing the shot, and trying to get a reading at the same time. Hopefully they are weather sealed.
There is also the matter of what angle of view it will cover. I've used other older meters, and currently own a VC II, and with the rear facing screen on the proposed model, it will make it easier to read and make the necessary shutter and aperture adjustments as long as one can remember what the last setting was, and which way to turn a dial to match the meter reading. Otherwise it will be like any other meter, you need to move the camera away from your face to make any adjustments.
