very good
the spring of the laser head was missing so the laser was not working, cause no contact whit the battery ,needed to improvise a spring from another gadget to work,still need to weld the spring on the contact surface of the laser head so it does not fall of when i change the battery and it is a bit loose has a slit movement on left and right so it can not be accurate cause of that no matter how much u try to adjust the laser,need to improvise some thing to keep it tight otherwise its crap
