Caudabe Sheath vs Synthesis

[RayLancer]

I love their Veil XT cases (for my iPhone 6S) but I hate how the case gets loose over time like most minimalistic thin cases. I was looking at the Sheath and Synthesis cases and people seem to really like them but I haven’t seen much about durability. Do these cases get loose over time also?

I have the black sheath for the I7. It fits great and hasn't got loose so far.

I really like the synthesis. Just a shame it never finds its way to amazon
