I found this in a drawer on a shelf at home. Everything in the photos is included. I tried putting AA batteries in the battery compartment without inserting an MD, but the display didn't turn on and it didn't do anything. I don't know if I'm doing something wrong because I don't know how to use it, or if the unit is broken. I don't have a charger or gum batteries, so I haven't been able to check those. The main unit has many scratches. The lid for the gum battery compartment feels loose. It doesn't open on its own. This is a junk item, so no warranty is provided after purchase. Please understand this before purchasing.
