I own Sheath case for iPhone 13 Mini for several months, and that is awesome case. That is why I was quite disappointed with Sheath case for iPhone 16e. Its texture is just unpleasant in comparison to one of Sheath for 13 Mini. The buttons of Sheath for 16e have cheap looking anodised finish, whereas those ones in Sheath for 13 Mini are from the same material as the case and so pleasant to touch them. The case for 13 Mini has rounded rear side, whereas one for 16e, being more bulky, has more squared edges.
Overall the case is good, if to compare it with cases from other companies, but it is quite unthoughtful and just mediocre at best in comparison to the case of the same series for 13 Mini.
To be honest, I think that such mediocre quality is applicable to other Sheath cases - for iPhone 15, 16, and 17 series.
