Reversing Goggles

Tricky to assemble and glue so that everything lines up and in the end I had to adjust the alignment of one finished prism with tabs of insulation tape to get the vertical alignment correct in the finished product. The view image is also small, but they are efffective and do exactly what they are supposed to do. Just don't expect panoramic vision. I think it would also be worth an extra tenner if they came ready assembled.

Great glasses to have fun ;-).

They didn't send anything.

Have not received.

Construction was difficult because glue was not included.

99% you would need a glue to fix lens, but there is no glue in the package, so you buy it separately. Manul is the worst I ever seen - you need an academic degree to understand it. Also red gum is not good quality - mine was deformed :(.

Excellent and well made. I am an optical engineer and am very picky. This is well designed and delightful to use.

The only reason I gave it 3 and not 5 is because the assembly required (which I obviously f***ed up).
To have my clumsy ass glue (not included, and you have to guess what type you need) the prisms to the holes in the cardboard turned out badly for me, now one lens is foggy. But that is completely my fault... still a pre-assembled (at leased pre-glued) would make me give it a 5+ stars.

A bit finicky, but alright.

Cool stuff. It really turns the world upside down. Challenging and fun, not just interesting.
