Adjustable Speed and Direction: 0-35000rpm nail filer electric with adjustable speed controller, it is user friendly for beginner. Forward and reverse rotation direction make it easy to use for both left hand and right hand.
The Nail Tool comes with six easily removable, grinding and polishing bits.The chuck’s collar grip is very well balanced, and the tool does not vibrate at its highest speed.Each of the heads is designed for precise work, and the tool makes it easy to operate.The translated operating directions might seem to be a bit confusing, so here are some added comments:The Power Button seems to be the brains of the whole operation.There is a “long press” (2 sec) to turn it on and off.If it is turned on, short pressing will control the speed level, which you can ascertain by watching the bar lights.If it is turned off, a short press of the Power Button will light up the bars to give you an indication of the remaining battery charge.The Control Button, NOT the Power Button, changes the rotation direction from clockwise to counter clockwise and vice-versa.Given the laminated structure of a growing nail, the rotation direction is important for a left-handed versus a right-handed user.The first charging takes about two hours.Afterwards, it requires slightly more than an hour to recharge.If it is charging, the bars at the base will blink until the battery is full again.As for the duration of a single charge, the device is reasonably powerful for 20 to 30 minutes at its highest speed.Because it is powerful and it has three speed settings, I’m tempted to test it as a poor man’s dremel, especially because it costs much less!It does not come with its own USB AC/DC charging adapter.The specifications say you will need a 5.0 V adapter that charges at 1 Amp.Unfortunately, most 5.0 V USB chargers put out 2 to 3 Amps.This excess current will charge it faster, but at the expense of its battery’s lifetime.Just keep this in mind when you have to recharge it.I really like this battery-powered device for fingernails and toenails.Overall, it is well constructed for a battery operated Nail tool, and it is worth the investment.
Other than the distasteful smell of the grinding of the nails, this rotates and works strongly. It is quite a powerful tool, but very but small and easy to handle as well. If you are into shaping your own nails like me, you will definitely enjoy using this.
I found this HengYuaoler Electric Nail File Set perfect to take along during trips or anywhere you know you will have time to do your nails, just be sure to charge it first and take your charger with you. I enjoyed the compactness of it and the easy use. Being able to charge it before use was the best part except depending on the speed the battery life shortens. The filer was easy to hold and was not that heavy after prolonged use. Switching out the drill bits was also very easy and quick.
