Great product, very high quality lenses, extremely well thought out design and implementation and highly comfortable fit. One design consideration I have found is that looking back in tight confines to the same side as your mirror requires training yourself to look under your arm or lifting your lenses slightly to clear the bulk of the mirror. It's novel if you aren't used to that but as someone that used to wear a top mounted mirror, I had a high blind spot so I was familiar, just wasn't familiar with where this would be. So proper familiarization of where this blind spot will be is critical. But overall, the Tri-Eye is a huge win for me and I have loved the step up to lens and mirror in one.
