Anyone tried aftermarket .85 eyepiece attachment?

I've got an M3, which I love, but it's hard to see the entire frame line because I wear glasses. I've seen this gizmo that claims to turn a .72 into a .58, or an M3 finder into something like a .72. Has anyone tried it?

I've used the 1.25x magnifier by the same manufacturer and it works well. Its sharp and free of distortion, but it does reduce brightness a bit and it sticks out from the camera body enough to poke your eye out if you're not careful.

Interesting. I also have the 1.25x version of this and use it if I'm using a 90mm on the M8.

I'm a wearer of glasses, and wonder if the the .85x would get me "close enough" to use a 35mm on the M3 without an external finder. I know the framing will be a bit on the tight side, but still... at this point I really don't see anything outside the 50mm frame lines without peeking around the edges.
