The Bose sunglasses are great and the progressive lenses are high quality. The product itself would rate five stars. My only issue was that it took a month to get them, Lensabl doesn't keep their web site up to date. For a month the status on the page reported that the glasses would be shipped in six days. The customer sales rep was polite and gave me various reasons for the successive delays. However, I was never told of delays until I asked nor was I informed of status in any way without my sending an email. In the end, I had to threaten to cancel the order. I don't know if the string of delays was an exception, but don't expect the product to be delivered quickly.
