Lifetime warranty was one of the main reasons I purchased these overly priced glasses. My frame has broken numerous times both sides!!! When I contacted the company here is the response that I was sent. Sorry to say but we are no longer in the sunglass business. We do not have any replacement frames or lens left. Sunbuster has closed down Evan Wagner Director of Operations GustBuster 855 Conklin St Suite O Farmingdale NY 1173* 631.391.9000 (phone) 631.777.4320 (fax) www.gustbuster.com So how are they going to honer their warranties? This company is still doing business, why are they not honoring their commitment? I would think they would find this to be very bad business indeed.
