Ratings and Reviews for  Reversing Goggles

4 / 5
The reversing goggles are great fun! However they require a *lot*of assembly: they are really more of a diy goggles kit so people should be prepared to have to spend a bit of time preparing them. It would be good if they were supplied with the epoxy needed to hold the prisms in place, and the enamel paint to cover the open faces. But once they are together they are fun to play with - we will be using tem with psychology and architecture students to teach them first-hand about vision and space.

They do require some assembly. I will have another look at the description to see if we need to make that clearer.

There are issues around selling glue, which I suspect is why the kits do not come with glue already supplied.

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.

Construction was difficult because glue was not included.

Hi

I understand. However there are regulations around the sale of glue, and proof of age is sometimes required. So the German company who supply this kit have taken the decision not to include glue with the kit.

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.

Very disappointed by the product. The item is definitely not what i expected. 1 ) The two prisms do not fit at all the cut of the glasses, making them move, or even fall. 2) Even if adjust it by yourself with paper.... it well never be accurate enough, so your view is never straight. 3) The field of view is tiny. => This is a product you won't use for more than 5min. I wanted to do experiments wearing upside down goggles for a longer time. It's a failure. I wish I coul.

It would have been nice to have English instructions for the product. They are also missing a way to hold the lenses to the paper cards and I need to find a suitable 2 part epoxy to glue them together.

I assembled with a little glue on edges (they were lose) but this would show in the reflected image.

Serious assembly was required of the inversion goggles - without precision gluing the things didn't work as advertised. A little pricey for that, in my opinion.

The goggles worked fine but getting them to work was hard and the crystals keep on falling out.

The goggles do not provide a clear vision. The field of view is divided into 3 parts and this makes using the googles very uncomfortable. Would totally never bought this if I knew. Will not recommend to anyone.
