These amazing Reversing Goggles allow you to view the world upside down! The plastic goggles hold two Dove plexiglass prisms, which invert the image. Alternatively, you can adjust the prisms in order to create right-left inversion.

Since the time of Leonardo da Vinci (1452 - 1519) people have wondered about the fact that the images of the world that fall on our retina are upside down, yet we see the world the right way up. Back in the 1890s the American scientist George Stratton conducted an experiment to see what would happen if he viewed the world through an inverting prism. He found that after 4 days, his brain started to compensate, and he could see the world the right way up again.

We are not suggesting that you recreate George Stratton's experiment. However, it is fascinating to wear the upside down googles and try to shake hands with someone, pick up an object, pour water from a jug into a glass, try and write, or find your way around (with someone else there to guide you of course). When we view the world normally, our brain reverses the images on our retina in both the up-down and right-left directions. These prisms reverse the up-down direction only. However if you rotate them by 90 degrees, they will then reverse left-right instead.

The kit includes the lightweight, ventilated plastic housing, two prism holders in MDF (medium density fibreboard), two high quality Dove prisms in lightweight plexiglass giving a 35x20mm view, plus a small file for smoothing edges. A small amount of assembly is required. You will need a protractor in order to measure a right angle and some 2 part adhesive which hardens quickly. Optionally, you can apply some black paint to the prism surfaces which are not needed, which will improve the picture quality slightly. Suggested Age 18+. Made in Germany.

Watch Alan Davies and Phil Jupitus trying them out on QI in the video.

Safety Notice. Wearing these goggles will cause you to lose your normal orientation. Do not make any movements while you are wearing them which could cause you to fall and injure yourself. If you want to examine the effects of inverting your vision, you should wear the goggles for at least an hour. However some people may feel unwell if they wear the goggles for a long time. If this happens, discontinue their use. We probably don't need to say this, but don't drive, drink alcohol or operate heavy machinery while wearing these reversing goggles!

Fantastic adapter for international travel
Style: Type C/G/A-Most Countries-3FT
This adapter worked as intended when needing to charge devices in Europe. The adapter was easy to attach to the plug and the cord length came in handy for sockets that were in hard to reach locations. The only thing is it does take up some space in luggage, so make sure to account for that. Would definitely recommend for international travel.

Stunning Automatic Watch With TopTier Durability and Precision
Color: Grey
“I got this Tissot PRX for my cousin’s birthday and bro fell in LOVE instantly. This thing keeps time like a beast, never slows down, never lags. Automatic movement, so no batteries, no drama. Durability? Stupid good. You can hit it, bump it, live life rough, it still looks box fresh. Size wise it was almost perfect. I just had to remove two links, nothing big. It’s light, functional, comfortable, doesn’t weigh you down, doesn’t get in the way but more importantly I can say this watch is in everyone’s eyesight when we wear it. Cause of course I had to get another one! Basically. I gave him a very nice piece as a gift, and now he’s walking around like he owns Switzerland.

Excellent value for an automatic watch, keeps VERY good time.
Color: Grey, Color: Grey
I've only had the watch for a day but wanted to leave a quick review on it to share a couple of notes. So far it keeps VERY good time, better than any of the automatics I own (including a Rolex Submariner, Tag Heuer Aquaracer, Tag Heuer Formula One, and several other sub $1k watches). I set it to an atomic time app on my phone yesterday and 24 hours later it's still SPOT on - hasn't gained/lost even a 1/10 of a second. I was shocked to see it's kept PERFECT time for the last day, I'm really blown away so far. I've worn it the entire time, we'll see how well it keeps time while being stored in a winder. This picture shown is the watch with a 22mm leather band on it, fit's without any issues (just need to squeeze in the leather a tad). I doubt it would work with a 22mm metal bracelet, but leather works great. Just FYI since the 21mm lug width is kind of odd. The face isn't quite a lustrious as the images make it look, but it's still a great-looking watch. For a sub $1000 automatic you can't go wrong, this is a fantastic watch at a great price. It'll be my daily driver for some time I'm sure. If I have any issues in the future I'll update the review.
