Great glasses to have fun ;-).
They didn't send anything.
I am very sorry but the Reversing Goggles are currently out of stock. We e-mailed you on March 31st 2021 to let you know.
More stock is on the way, and as soon as it arrives, we will ship your order.
Have not received.
Sorry. We were out of stock of this item, and as it missed the date for the science fair, we refunded your payment.
Construction was difficult because glue was not included.
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.
Skittle disapointed from the googles cause you don't see one good picture.
