I do not like to give negative reviews, however, the product recieved was defective, ie missing a Polo logo. It does function, but it is not perfect. It took 3 weeks to deliver, and the customer service was very slow. I asked for a replacement but they said its on back order. Finally, 4 months passed by and finally they asked me to find another similar style. Which I felt might not be any better. I think they tried to work with me but ultimately I was not fully satisfied. You usually get what you pay for any business. I now have a pair of Polo glasses that is missing a logo but it functions. They were not willing to give me a discount nor give me an answer as to when the back order will arrive or if it ever will. Major let down.
