"Absolutely the best sunglasses ever owned. These glasses are light weight and the arms don't put pressure on your head or ears, can wear these all day long. I have owned several top named brand sunglasses and nothing compares. Muai Jim has the BEST customer service, after owning this pair for 4 years and sitting on them, they repaired the frame within 1 week for the cost of shipping. You can't man-handle these frames, keep them in the case when not wearing and be careful when cleaning the lens."
