Great show but ...

But because there is a small problem, the digital display is very weak. In good light conditions the two small screens are readable, but as soon as decreased brightness, we see nothing more (it must find the right angle and a light source). The backlight (a pretty cool electric blue) are side does not help to better see the two small screens!
In the end, I find it regrettable that you can not adjust the contrast of these two small screens (I do not speak on the 3rd phase of the moon) leaves that hold the stack 2 years instead of 3 ...

If possible I will give 4.5 stars out of 5
