Number of speeds
The number of speeds at which the electric model can operate (see "Type"). For different nozzles, different speeds are considered optimal, and even for the same one, several speed modes can be used, depending on the desired processing intensity. Thus, the more speeds — the wider the capabilities of the device, the more accurately you can choose the best option depending on the situation. For maximum accuracy, however, it is better to select a model with smooth adjustment (see below), however, if this moment is not critical, fixed settings will still be more convenient.
Maximum revolutions
The maximum speed of rotation of the working nozzle of the set. The higher the rotation speed, the more performant the effect will be. But more is not always better, especially for sensitive people with delicate skin.
Usually, models with a maximum speed of up to 5,000 rpm are more suitable for processing natural nail tissue and cornea. Cutters with a maximum speed of over 5,000 rpm are already capable of processing both natural nails and false nails made of acrylic and other synthetic materials.
Professional grade manicure sets can have a maximum rotation speed of up to 30,000 — 45,000 rpm and even more.
Cover/case
The presence of a cover or case in the delivery set of a manicure set. The main difference between these devices is in the materials: the covers are made soft, the cases are hard. In addition, for a number of reasons, the first option is more popular among instrument kits, the second — among electric models (see "Type"). However, the purpose of covers and cases is identical, so in our catalog they are combined into one item. But this purpose is to ensure ease of storage and transportation: each tool or nozzle is placed in its “seat” inside the case / case, which minimizes the likelihood of loss or damage in contact with foreign objects.
Note that such equipment is practically mandatory for modern manicure sets of any type; options without covers / cases are practically not found.
