It is relatively fine, very well marries the G3 and the flexible part linking the valve to the rest of the shell appears strong, which reassures the aging of the hull.
The circle is finally a border plexi, which embellishes animation (a small halo of light just beneath the plexi) when you turn the phone mode "quick circle"
Regrettably, LG did not like Samsung, namely to replace the shell of the phone directly with that of the hull story to gain a few millimeters.
In short, very satisfied.
