SDG #338 Sequre ES555 and ES666 Electronic USB Screwdrivers

Sequre has moved beyond soldering irons into powered hand tools, and the ES555 and ES666 are its versions of the small USB rechargeable electric screwdriver that has become a staple of repair benches. Both are aimed at the same job: removing the tedium from dozens of identical fasteners on laptops, games consoles, phones and small appliances, while still allowing the last quarter turn to be finished by hand so that a thread is not stripped or a plastic boss cracked.

The review examines where the two models diverge. Handle format, torque delivery, clutch behaviour, the bit set supplied in the box and the charging arrangement all differ enough to matter when choosing between them. Bit quality is significant on tools like this, because a cheap driver bit will round out a Torx or Phillips head on a screw that is already thread locked, and the included bit selection determines how much existing electronics work the tool actually covers.

Also covered is what happens electrically when the motor stalls or reverses, which is where many budget screwdrivers show their weak points, along with practical handling notes such as balance, whether the driver can be used comfortably as a manual driver when the motor is off, and how long a charge realistically lasts across a working session.

The useful conclusion for a buyer is whether the extra spend on the higher model buys meaningful capability or merely a different form factor, and whether either driver has enough control for delicate consumer electronics rather than only general assembly work.
