[OM] Experience with Beattie Intescreens

[Peter Koch]

Hi,

can anybody, especially somebody in germany, tell about his experience with 
Beattie Intescreens in an OM 3/4 (Ti) ?

I am a lifelong eyeglass wearer and need the viewfinder more bright.

So what i want to know is, will i better look through the viewfinder, when i 
take an Beattie Intescreen 
82404: Plain matte, w/ diagonal split image NO grid lines.

in an OM 3.

Excuse my technical english, my college time is more than twenty years away.

Peter
