I've ordered two sets of these inserts and on both occasions I received them faster than the 2-3 week time-frame that Optics Planet quotes for delivery. The lab got my prescription correct, but then again mine is simple astigmatism.
These inserts work great with my Sawfly shooting glasses and my sunglasses. There can be some stray reflections under artificial light, when looking outdoors from indoors, and I would imagine the reflections during night-time driving would be annoying. This is probably an unavoidable artifact of looking through two layers of polycarbonate separated by a small air-space. I'm sure all Rx inserts have this problem under certain lighting conditions.
For daylight, outdoor use, these inserts work great. I hunt, shoot skeet and sporting clays, and ride an ATV a lot and these inserts get the job done.
Pros: Easy to clip into glasses
Cons: the only frame color option is grey
