I am pretty hard on eyewear and needed a more affordable option. I never believed that they could get the proper information to make glasses correct over the internet. With the help info that ZENNI provides to get proper measurements, it is harder to make a mistake than to get correct info. Also, they say to expect delivery in 14-21 days... from order date to delivery was 11 days. Three days early! I also took advantage of the single click reorder option as I left that pair of glasses on the hood of a vehicle and was unable to retrieve them. Looking forward to my new pair...
