Very effective & aesthetic mirror film from the lighter (outside) side and tolerable level of dimming with minimal colour hue and fairly low reflectivity on inside. Fitting took some practice to get right, if doing smaller window sections I'd recommend cutting, with a very sharp knife, to the exact size needed before fitting, aside from that followng video guide works well; use plenty bubble spray and check from both sides for bubbles. Be aware the reflection/ transmission ratio is dependend on the corresponding light level for either side, ie. at night with the lights on it acts as a mirror to inside and outside sees in.
