The front lamp is perfectly in every respect: to surpass luminosity hardly support simple and practical. The battery compartment is a little difficult to close, but oh well. The taillight is also a marvel of luminosity. Here comes the downside: the rear light bracket made of plastic is not stable enough. Mir broke without apparent force in a few weeks just from. Now the rear light can no longer install. That must be revised! Also, want to be able to buy front and rear lights individually.
