3 pieces Point Laser Pen Fixed Foucs,Red & Blue & Green for Pet Cat Toy Wavelength 532nm, Outdoor Tactics LED High Power Hreen Light Beam Interactive Training Tools

18 days to receive (with free shipping), red & green work, but blue does not. No instructions saying what batteries to use in package, but 2 AA batteries will make red & green work. Bought this because it advertised blue laser. Description says no batteries required. Fixed it myself, needed longer electrical connection internally.

Advertised batteries included. No instructions on what batteries to use either. I would not recommend.
