Simply outstanding. Easy to book, and Luis arrived precisely at the appointed time and restored a 40 year-old pair of Ray Ban Aviators that had belonged to my father - of priceless sentimental value. He meticulously replaced the temples ('arms' - hard to find), replaced the screws, and tightened them up. Good as new. Luis also rebalanced another pair of sunglasses that I had sat on. All for the excellent value of $49. Extremely polite and helpful - even put the old parts in a baggy.
