The "try at home" service was excellent! I was very pleased that the person who answered the phone was also able to answer my various questions about, for example, how many pairs I could try and whether I could exchange for a different selection. The chosen pairs arrived very quickly for me to try, carefully packaged and returning them was a simple process. Having spent hours searching unsuccessfully in my own optician's premises and waiting while they ordered alternatives for me to try this was, in the end, where I found the frames I was after all along - and took them to my own optician to glaze. The perfect solution! Thanks for your help, GFL!
