This product is a lifesaver for small items. It plugs into your cellphone (android or iPhone) and instantly works as a mini sterilizer. The LED puts out discrete germicidal wavelength to target the genetic material (DNA or RNA) of the microbs and stop them from multiplying, thus, it eventually kills the microbs. Its mini size allows you to carry it basically everywhere you go. It consumes so little power that you can almost keep it working non-stop. Not only does this kill as many germs, bacteria, and viruses, it’s non-toxic, less damaging to items like your phone, and can actually clean items that you would not be able to wipe down like makeup brushes and toothbrushes.
