J 3 Came with two printed A4 sheets - English and Japanese instructions - English not perfect but comprehensible. No batteries included, requires 4x AAA.Left hand button is damaged on my unit - it feels stuck down and does not click like the other ones do. Makes it very difficult to set the duration.Unit advertises itself as not water resistant (so do not use it outdoors). Not sure why Amazon is asking me to review it's water resistance.
