Review: Looks good, fits right, good quality - Lots of things to like about these glasses. They arrived with a hard shell, zip around case that has a built in clip for attaching to backpacks, etc. The lenses are not warped and the glasses feel comfortable. They have a reader frame that is super easy to snap in and out. I posted a video and hope it helps.
Review: Look awesome, but ear piece falls apart easily. - I've ordered two pairs from them and loved them both. However, both pairs one side of the ear piece where it collapses has broken. Be very gentle when closing and opening the ear pieces as they seem to be very fragile. I have to leave the newest pair open so the plastic around the metal piece doesn't break off. The last pair I had to super glue open.
