About company

Initially, the South Korean companies Saeshin and Saeyang produced only dental and dental equipment. But with the growing popularity of the nail service, they expanded their range to manicure devices. Thus, Saeshin introduced the world-famous Strong line, and Saeyang introduced the Marathon series. Through years of hard work, these campaigns have been able to achieve worldwide recognition and gain the trust of their clients.

A series of Strong manicure devices includes more than 10 models of nail drills. The very first, and therefore the oldest of them, is the Strong 90N model. Most often, this device is equipped with a Strong 102L handpiece, and many nail technicians prefer this set to any other models for its high reliability and quality. And this despite the fact that subsequent models have a more attractive design and are equipped with more functionality.

And the most popular in this line is the Strong 210 nail drill. And it is not surprising, because its unsurpassed design and additional, simply necessary functionality attracts a lot of attention. This device is also equipped with the most common handpiece, such as Strong 105L, Strong 107ll and others.

Recently, the company has released the Strong 211 (B135). This is an updated 210 Strong but with a brand new H400 handpiece. The maximum number of revolutions of the micromotor is 40,000 rpm, while he received a double system for fixing the nail drill bit. New bearings installed in the handpiece ensure minimal noise and heat levels, and this technology is called "Zero Vibration Technology".

One of the most powerful models is the Strong 207S, which comes with the Strong H450 handpiece. The fact is that such a set in a duet gives the highest technical characteristics and is the most productive. Strong 207S, with its 5.0 Ncm of torque, is ideal for feet.

As for the Marathon series, these are no less common devices than the Strong, but not as reliable. Marathon includes more than 5 different models of routers, the most common and popular are Champion 3, Escort 2 Pro, K35 MINI and N7.

The most popular Champion 3 model is a small, simplified nail drill. With its 45 W, Champion 3 can even be used to perform pedicure procedures, but only infrequently - 1-2 times a day.

Escort 2 Pro is equipped with additional protection measures (automatic overload protection system). The presence of two transistors at once ensures uniform distribution of voltage and heat between them and the radiator. Therefore, Escort II Pro is considered a more reliable model compared to other marathon runners.

The Marathon N7 model features a built-in feedback function and automatic overload protection, which is well suited for a pedicure.
