3Dstereo Stereo Wide-View Viewer for Prints and Monitors

Super nice, no more flat paper eye glasses. This work very well, everything in focus from far or close. They are great.

These glasses work for playing Spot the Difference games. Haven't tried them out for other uses. They are a little heavy so are a little uncomfortable to wear very long and need to be handled carefully so as not to break the ear pieces. It takes a little getting used to and some adjustment, but they do work.

The view is very clear. It may take some getting used to to use. So far I don't know about the longevity of them but I figure if one doesn't treat them like the Orangutan from the viral sunglasses video they should last just fine.

The viewing part of the glasses is very good at melding two separate images into one, so that is really great. But the temple or side pieces have very poor engineering and thin plastic. I heard from two friends theirs broke very quickly, and despite being so careful mine also broke after a couple of months in intermittent use. The viewing glass area itself is quite heavy in addition. To keep using the glasses I had to apply heavy silicone to keep the temple pieces attached. This could be a wonderful product if those side pieces are redesigned so the flimsy living hinges are replaced with something that lasts.

The good news: the viewer works quite well for effortless viewing of side-by-side stereo images. A friend who has never been able to see simulated 3D with "magic eye" prints or cardboard viewers, was able to almost instantly get the mirrors set correctly and see 3D side-by-side images on my computer using this viewer. The adjustable mirrors allow viewing on anything from the size of a tablet to a big-screen TV. The bad news: forget about hands-free viewing. The "hinges" on the earpieces are flimsy plastic tabs which broke off after a few months of use, meaning you need to hold the viewer in front of your face with one hand.

This is my 2nd pair. Hoping the ear stem will not break off. Had my other pair 6 mos before 1 stem broke. Works great for my purpose.

Cheap piece of junk Image adjustments did not work. Would not recommend.

Earpieces were uncomfortable before one broke. After it broke and I couldn’t tape it back, I pulled off the other and the viewers work just fine on 24” monitor or iPad when you hand-hold. Lets you easily go back and forth when controlling your computer then viewing when ready. Also has worked well for me on 8.5 x 11 prints. Doesn’t work on iPhone (Plus) because of size.
