Bought recently as a gift for my husband. The device is heavy and heavy. Came intact, the whole set is assembled, works. Points are nonsense: scratched, it is difficult to look into the glasses, and it is doubtful that they are needed at all. The beam hits 3-4 meters. Further it is hard to see. The color of the beam is still more visible red. There is a small error (but it has not yet been thoroughly checked). If it is crooked, it squeaks. The husband is happy as a child. In principle, the purchase is good and necessary for household chores.
