Ordered 10 pairs of glasses over the last 5 years never had any problems. The last two pairs I got 2 months ago. One of the pairs had small scratches all over them, despite having scratch resistant covering. I returned them and was told I must have scratched them whilst cleaning and would have to pay another £40 to have them re coated with the same failed scratch resistant coating. Having worn glasses daily for over 30 years I know how to clean them and also realistic about the conditions lenses should be in after 2 months of wear! Very poor customer service. Avoid completely I know I will from now on.
