I don't have a TVA to compare but have noticed that the full metal clasps feel and work great when I'm wearing them but on the case cushions some models want to latch easily and others need some manipulation, raising the lower side of the clasp, to get it to latch. My D and TFG latch easy first time every time on the cushion but my TB and GD don't want to latch every time and need some work.The clasp on the TVA seems to work a lot better than the ones on pretty much any of my other metal squares (SS or Ti), i.e. it's working like a clasp on a watch at this price point should work: easy latching and unlatching. Do you guys notice this as well or is this a fluke?
Because it never happens when I'm wearing it I hadn't given it much thought or a close look but I'm sure it's basically caused by the cushion having too much give to push the lower end of the bifold up so the pin catch.
