How can you tell a Rotary Machine from a True Digital Permanent makeup Machine?

What is the difference between rotary permanent makeup equipment and state-of-the-art digital equipment?
Many companies market themselves as digital, or digital control but how can you tell if you are truly purchasing a digital machine. Well, the true Digital Permanent Makeup machines are considered the “Rolls Royce” of all permanent makeup equipment and are only manufactured in GERMANY (like BMW) not china. Digital Permanent Makeup machines do come with a hefty price tag and can range in price from $2795-$3500. A rotary machine can be easily separated from a digital if you know what to look for.
Does the hand piece (pen) plug directly into the power source (plug or wall outlet) is it battery operated or wireless (rechargeable Batteries)? If yes, then it is not a True German Digital Machine it is a rotary. Be especially aware of machines coming out of China the quality tends to be extemely poor, and does not come with a warrenty. Even worse if they are not a reputable business and go under, you will have to purchase a whole new system as to needles are not univeral. Companys like Kanagawa market themselves as digital when it is just battery operated they retail for $49-$55 a piece. Big difference from a true medical Presion quality of the Noveau Contour 1000's
A true Digital machine regulates the speed of the needle based on the thickness of the skin. The needles come in a cartridge that is pre-sterilized, so there is no need for an autoclave. It self adjusts and maintains the same speed , kind of like a car on cruise control going uphill, you can hear the engine rev up yet it maintains the same speed you set it on. The digital Permanent makeup machine is the same concept. A true German Digital Machine is easily detected from a fake….
The Hand Piece (pen), on a true digital machine should plug into a digital unit (about the size of a microdermabrasion machine), and that unit plugs into the power outlet (plug or wall outlet). The digital unit controls the speed and precision of the needle in the hand piece. Plain and simple, it is the brains of your equipment. If your equipment is not plugged into anything but a wall or operated by a battery then it’s machine that can only be adjusted by the technician. Rotary equipment is a great backup to digital so technicians should know both methods since the likely hood of owning two (2) digital machines is unlikely due to cost factor.
