Grafik Eye QS vs WPM?

[schalliol]

What advantages does the WPM have over the Grafik Eye QS? It seems like the Grafik is a bit more flexible and one can just get the full white cover. I understand the WPM is usually used for fairly hidden devices, but the Grafik could be used in a similar way. Is there something I'm missing?

It's 1/2 the price.

The wpm is for strictly hidden,,,,grafik eyes are easy to adjust levels and have keypads on front. They work stand a lone...wpm have to have a control system to control individual loads.
