I got 2 pairs. One pair, the sunclip works very well and is very easy to put on and remove (Black 353s), the other pair (Brown Horn 353s) the clips are either too tight or the frame of the glasses are a bit thicker. I switched the sunclips around and the Brown's sunclip slides onto the Black frames with a bit of stick and the Black's sunclip slides right onto the Brown frames. It seems the clips are a bit too tight on the Brown's sunclip and a pair of pliers should be able to remedy this.
The frames themselves can fit a wider face.
The case is functional, semi-rigid, with a magnetic clip that doesn't close completely if you put your glasses in there with the sunclip attached. There is no separate compartment/case for the sunclip.
Comes with a cleaning cloth.
Is there really not a single photo of someone wearing them without the sun clip in the entire internet? One would assume if a product was made by a famous designer there'd be a lot of photos of it on instagram at least...
