Actually a good idea, an essay receives which the performance and settings of the existing system flash. After unpacking which somewhat disillusionment wide. The rubber boot is a bit short, the velcro is trying to keep the unit from the flash. The light-emitting surface is reminiscent of processing and stability rather to blister packs of children's toys. The manufacturer's logo consists of a printed piece of cardboard, which was clamped behind the plastic. Unfortunately, a share of at least 70% of light output ends already at the top. With a little more attention to detail and a better reflector could really pursue the idea.
