I was skeptical but the cost of My glasses with a severe astigmatism and My tight budget has forced Me to seek other avenues for My eye glass prescriptions.
I followed the instructions and was pleasantly surprised that it gave me a prescription just a bit stronger than My last professional one from 3 years ago
Instructions say the more I do it the more accurate it is, so I will be doing it on a regular basis.
Fits iPhone 6s very well.
It is a little awkward with Your non dominant eye but I did get the hang of it.
Also if You're having trouble seeing the lines move the eye piece around not the phone the most comfortable spot didn't seem to be the right angle most of the time, also don't use it directly under a light for Me the eye piece didn't cover My eye completely and back ground light can cause glare through gaps
