The product has some flaws compared to a similar lamp but much more expensive game I own - Feeling of lightness / fragility of lamps and fixtures - Fastening systems are weak: I have broken after one month - The plastic of the rear lamp is not perfectly transparent and attenuates (very slightly) light - The cover of the front lamp button left after only a few uses
By cons beat the price considering that the lamps are functional, visible, each have a fixed mode and a flashing mode (1 flashing mode for AV and 6 lamp and lamp AR). Small seals are present and the lamps have stood a one hour ride in the rain.
