Just to start, I do really like these glasses. I purchased them and all three of the lenses (will be making a video soon). They are lightweight, look great in the matte carbon and I get compliments. My two issues Ive experienced however are two things. First, one of the nose pieces keeps falling off. Which is an issue. Second, the simple "Pop and Play" of the lenses is not the easy. You REALLY have to push to get them in and out. Once you get the hang of it it's okay, but I got nervous I was going to snap the glasses.
Side note, there are films that are on the lenses, remove prior to snapping in... Ask me how I know... :)
