I bought these a little over a year ago primarily for running, but also as a general use pair for driving, fishing, and other outdoor activity.  Look, they're $30, and I'm not buying them for fashion--I'm buying them for utility.  And to be honest, they did exactly what I expected.  They weren't too tight, but the rubber nose and temples kept them snug on my head so that they didn't shake or slip when running (I don't have a wide head).  And the vision was solid.<br /><br />A month or so ago, I was bummed when the right lens cracked a bit while in my carry-on luggage.  Last week, I noticed that JiMarti offered a warranty on breakage, so I sent an email to the company on their website with a screenshot of my Amazon order.  Today, a replacement pair showed up in the mail.  Thank you, JiMarti!  I'm looking forward to many more months of active use.  They were worth every penny I spent on them.
