Engo 2 - Heads up display Review - First Impressions 

Thank you for the comment, the only problem is that the more features you pack on the sunglasses, the heavier they get and need a bigger battery. Kinda like the previous glasses I had, huge, heavy, and impossible to wear on a run.

Standard size.

I don't know. I use reading glasses and the numbers are visible and I can see all the stays just fine.

@@getthedubwilly I just purchased. Thanks for the reply

It is not as clear as I would like it, but I thought it was just my eyesight. You can adjust the brightness and location of the display on the app. Try that see if it helps.

@@getthedubwilly yeah same here. In the end I had the brightness too high (but I thought it looked good) but with that it’s so bright, it reflecting back on itself, causing the ghosting. So I’ve set it back to auto and it’s a lot dimmer. But no ghosting granted. I found using the supplied elastic to hold the glasses in place a good solution for them no slipping / moving. Look forward to seeing what you think of them after a few more usages. Rich

Yes, in essence a simple display of the information from the watch, phone, or other device like a bike computer.

Manufacturer says 12 Hours. I've ran with them for 3-4 hours, but I have not tested them straight through more than a few hours.
