I immediately tested it out upon arrival. I have bought other microneedling machines and had to return them within the next day. This one here I am keeping! It’s the real deal. This one actually moves up and down how it’s suppose to Vs. Other off brands I’ve bought would just vibrate. Maybe there is a good off brand one out there but unfortunately I couldn’t find it so I bought the real one this time around and I am super happy I did. I finally got the one I’ve been searching for. It is a little tricky to figure out how to start but the power light is the on and off button to just put your finger over it for a few seconds to do either or. Also it comes with 2 batteries, one charging twist on and one for direct current. It does come with the charger and the power box as well. It also came with 6 needle cartridges :)
