    все отлично работает, светит очень четко и красиво. Закрепить пока еще не пробовал на велосипеде. Доставка шла долго, скорее всего из за пандемии. Продавца могу смело рекомендовать!!!

    Bright! Good quality

  29. B***v

    27 дней доставки с отслеживанием до Отделения связи. Заряжается, светит, режимы работают. В полную меру тестировать буду летом. Брал за 1420р, считаю дороговат за его Смарт-начинку. Переднюю фару с light sensor брал за 550р в начале 2019. Вот это была цена – я понимаю. Магазин рекомендую. Продавец молодец – на вопросы отвечал. Была задержка на таможне 5 дней – проблему решили. Вывод – лучше заказывать из РФ, надежнее. 200р переплаты не стоят нервов и ожиданий. Всем удачи на дорогах!

  30. U***c

    Great product. The one I got from Amazon has an “auto-on” feature that this one does not seem to have but the quality is excellent. It has the “brake-light feature that is nice. It gets bright when you slow down.

  31. W***o

    Produto excelente, veio muito rápido, quando você freia a bike a luz fica mais forte como se estivesse em uma moto, bem legal, não fui taxado, comprado no dia 11/11/2020, postado depois de 2 dias, entregue no dia 01/12/2020, recomendo, bateria dura muitos pedais, acredito que uns 4 pedais de 2 horas de duração. Vem com dois suportes, 1 para o selim e 1 para o canote, vem o usb para carregar e manual, vem bem embalado na caixa original da ROCKBROS, vale a pena cada centavo. Paguei R$115,26

  32. G***r
