Last night I found a piece of Chriz’ mirror in the office basement. I remembered that I kept some pieces of my 2nd mirror, which arrived broken back in 2017.
So here is the comparison of
Far left: Chriz’ mirror (~3mm, ~24% transmission, ??? reflectance, light ratio ???)
Middle: Pilkington Mirroview (6mm, ~25% transmission, ~65% reflectance coated side, 59% reflectance glass side, light ratio 17:1)
Far right: Mirropane Chrome Spy (4mm, ~8% transmission, ~48% reflectance coated side, 8% reflectance glass side, light ratio 8:1 )

I couldn’t manage to have a picture taken with the test pattern shown on all 3 mirrors at the same time. But you could still compare with the pictures from the previous posting.

And with some sort of GUI:

Please note that though these pictures might give you a glimpse on “usability” for a smart mirror but may be misleading in terms of actual “mirrorness” of the compared products. 2-way-mirrors are simply waaaay less bright/reflective = darker than regular mirrors. I would not recommend any to be used as a makeup-mirror or in a bathroom or low light condition. Of course this is also true vice versa in really bright light conditions…

From “feels” I’d say that Chriz’ mirror has a little less transmission than the stated 24%. Given that Mirroview’s statement of 25% is true.
It is comparable with Chrome Spy’s “brownish” tint but has way better transmission. Might be a tad “darker” than Chrome Spy though.
I have to admit that the brownish tint might be a good choice if you like “schmoozish” mirrors anyway. I’d say that even on regular mirrors with a brownish tint you look “fresher” than you probably are ;-) Trade-off is the darker feel and the mirror probably being less color-fast.
IMHO Chriz’ mirror will give you the best results on displaying fonts as it somehow smoothens the pixels of the screen a bit.

Mirroview is a little bit brighter than the other two, but that might be deceiving because its tint is rather grey/blue’ish. So a reflected wall e.g. looks more white but its reflection image is a bit on the cool, technical side (see picture 2 next to lower right corner of the test pattern). All in all it probably might count as the “realest” reflection of all three. Due to its quite transparent characteristics it is definitely best if you plan on showing colorful videos/diagrams on your mirror as colors are shown with less variation than on the other two. On the other hand you will be able to see the display’s pixels if you look real close.

One last thing:
There is no “one-mirror-fits-all” on a 2-way-mirror setup! I suggest you get a set of samples and depict the right mirror for you on-site with your individual lighting situation.

@goldjunge_chriz

what about sandblasting the area? Is it possible for the material?

If illuminated from the back would it be enough to illuminate a person in the front?

I guess there’s no other way than trying it out by yourself…
But sandblasting sounds like the worst way to go to me.
I could imagine that there would be light bleeding into the mirror glass causing some unwanted effects (like a halo). To minimize this you should cutout the black foil (you hopefully put) on the backside of your mirror and put some opaque acrylic over the cutout. That way the light from the LEDs will get diffused before it enters the glass. Enough distance from cutout to the display is also highly advisable.

@tomster
thanks for the detailed and clear explanation ;)

Nice info, I have put off this project for a few years and just recently started back. Originally I ordered two way acrylic but they sent the wrong stuff so I gave up for a while. I just read online and found a link to amazon two way glass and it looked like MirrorView was the best but it was out of stock so I got the slightly darker tinted Mirror(Something from same company). It will get me going until I get it replaced someday.
