Another Classy WO product

I bought one of these from FLO a while back and use it on the odd occasion when I want to use my TV85 as a spotter or for objects low on the horizon where straight through would be awkward and a 90 degree mirror would be just as awkward in the opposite direction. It performs well and although throughput will never match a mirror, it does have it's uses and is built to a very high standard.
