I bought these during the Kickstarted campaign but wasn't 100% convinced on how well they would work. They took a little while to get used to but now I won't go cycling without them!! Would definitely recommend.

These glasses are down-right amazing! The ability to maintain your spatial awareness whilst cycling (especially near cars) makes this a game changing product for me. The sleek design and comfortable fitting just makes it easier to wear on any outing.

Thanks for the glasses, which arrived a couple of weeks ago. So far, I am pleasantly surprised, they do what they are supposed to do with just a slight turn of the head. It's always nice to back a Kickstarter that delivers.

Whilst I have the enviable position of being able to commute through the Peak District, and mostly off road, there are some road sections. Wearing the Hindsight glasses is a significant advantage. Vehicles are relatively infrequent, however the roads are narrow and heavily potholed, so awareness of what is racing up behind a massive benefit. I have found that I need to make a slight tilt to get the rear view, but this is so minor, and much less of an issue than without these 'superpower' glasses. Recommended.

Have you noticed how everybody takes it for granted a bad experience is automatically, unreservedly, unremittingly bad?It’s almost a given that winners only become winners after overcoming huge difficulties. And they overcome because they keep trying, keep learning how to control their own thinking until they become very good at it.
