I would give them no stars if I could. Have to go back every 3-4 months for new lenses as mine keep deteriorating. Not due to scratches, but because the coating on the lenses keeps coming off. The last time I went there they stated that I would be done in an hour. 6 hours later, they were finally done. Problem is, every hour that stated that it would be an hour. So, I couldn't go anywhere. Poor customer service and poor product.
