The newer generation model is smaller but the trigger mechanism seems a little stiff (borderline like it is binding along the sides. Though I think with some repeated use it will become smoother over time. I currently have the previous generation that has screws and a slightly wider body with a leather carry case. I personally like the older and slightly wider one because of its ease of opening it and cleaning any dust build-up or lint that worked its way inside. Another reason why I think it is better is because of how easy it was to make a laminate for the insurance cards where I can slide it right out and back in with no issues. The smaller form factor also presented a new challenge of trying to see how I could fit my insurance cards. There are other ideas worth exploring but I may need to 3D print an enclosure to see if it will work with the wingman add-on. Maybe bringing back the leather expansion option would appeal to some people for the newer generations of wallets.
