2UUL DA81 Rechargeable Polish Drill Pen

A light scratch on a phone frame or a dull edge can make a refurbished phone look second-hand. The 2UUL DA81 is a small rechargeable pen with spinning heads for polishing and smoothing surfaces during refurbishment.

The listing describes variable speed, interchangeable polishing heads, quiet operation and a rechargeable battery. It doesn't give speed, battery capacity, charging port or which heads are included.

When the DA81 helps

• Light scratches on a metal frame.

• Scuffs around camera rings or buttons.

• Rough edges left after filing a bent frame.

• Dull spots that stand out after refurbishment.

Polishing safely

Clean the surface first so grit isn't dragged across it. Pick the head for the surface, start on a low speed and use light, circular movements. Check often; it's easy to change the finish more than you meant to.

Keep it off glass coatings and screens unless the head is made for them, and disconnect the phone's battery before polishing near ports or openings. Recharge it after use so it's ready for the next job.
