With a full coverage of 42 UV/LED beads it is twice as fast as other 80W or 96W nails, preventing the circuit from overheating and thus extending the life of the LED dryer. With the UV and LED light beads embedded in the liner, this makes this nail scrubber perfect for treating not only regular nail polish but also large areas of nail polish with UV light, regardless of brand or type of most nail polish kits." The emotion sensor provides a fully automatic, touch-free experience without the need to press any keys. [Smart Sensor and Quick Dry] Equipped with an advanced emotion sensor, our professional massager automatically switches off when you touch it with your hand, without the need to press any buttons, and the built-in LCD display on the lid shows measurement times etc. Compared to standard UVLED lamps, our UV-LED dual lamps significantly reduce the curing time, thus reducing the possibility of dripping/dipping when applying multiple layers of polishing gel.
