Decent device worth the money. If you compare with BOSCH GLL 3-80, then purchasing it for a lot of money, you additionally take a footboard for it, which also costs money. And here, as it were, everything is simple and everything is already in the kit.

The fakuda apparatus (having a second builder at hand) can be calibrated independently. I think that this device is in no way inferior to Bosch, except that its equipment is made of not very good materials, but if you take care of it and do not drop it, it will last a long time and faithfully
