So, I've had a pair of square wires for a few years now and love them. The were at the time referred to as Square Wire 3.0. Recently, I bought some aftermarket lenses for them, and they were the right shape, but were way too large. When I inquired, I was told that they were the "new" square wires, that just came out in 2014. I love the idea of getting these new square wires that are larger than the ones I have. Is there really a new square wire model? is there a model number I can use to identify them?
