Air2 met expectations. Perfect for mountain biking and all kinds of other activities in the dark. Minus the length of the cord, which is not enough for the back pocket of the filler jacket when the lamp is attached to the helmet. Battery life is quite adequate. The smallest powers are enough for mountain biking, so there is time for a long run. The maximum power seemed good in the wet forest, in the snowfall the maximum feels like an exaggeration.
Really good quality and bright, battery life, I have been very satisfied. The small disadvantages come from the "need" to buy accessories, the basic package contains quite a few necessary components. The cord for the battery should also be a little longer.
Very good light output, battery life is really good and the lamp is really light! Big recommendation!
A qualified device in terms of both light output and ergonomics. Different light intensities are convenient for optimizing the operating time for different applications. The only small inconvenience has been that the strap going behind the neck easily disengages completely from the strap lock, which adjusts the length of the strap when closed. Thus, the strap comes off between uses when storing the lamp and putting it on again.
