I own the Titanium Ridge Wallet. Despite some shortcomings I love the design. I find myself constantly playing with it, even after owning it for a year. I do not find it hard to use, although that is a valid point for some, and I did not have any issues with screws coming off yet. The Ridge Wallet comes with a Torx screwdriver in case this does happen.
I paid over a hundred dollars for the Titanium version, and maybe that is overkill. And there are cheaper options. But I hate supporting knock offs. Please pay more for the original designers if possible. It's one thing to see it on Amazon with the millions of Chinese knock off listings, but its disappointing to see Drop endorsing knock-offs.
I won't judge if you only care about getting things cheap despite it being knock offs, but doing a group buy for a knock off is on another level of cheapo.
