Here’s a closeup of the specs from the paper insert.

The screwdriver accepts two AAA batteries (not included). The rear end of the handle unscrews.

You also get three tubes worth of 4mm bits.  I couldn’t identify them all visually (some are really tiny).

Fortunately, the Brando web page listing shows all of the included bits, spelled out.

It wasn’t obvious at first, but once you squeeze the black trigger to turn the bits in either direction (it looks like one long black button, but it’s actually a forward/reverse depending on where you press it), an LED light illuminates your work area.

The big question is: How well does it work?  I found that under moderate torque, the screwdriver seems to struggle a little bit and the LED light dims considerably.  Then again, the inclusion of all the extremely tiny bits tells me this was really intended for very, very small screws where torque may not be as much as found in this fairly ordinary light switch test.

Another interesting design choice: You must remove the bit from the screwdriver if you plan to use the included carrying case. It simply will not fit.

If you do normal handyman things around the house, you may want to reach for a slightly meatier electric screwdriver with more power. For lighter-duty tasks, the WOWSTICK 1fs could be a handy featherweight tool for very small screws if you’re doing a lot of repetitive work.

  2. I wonder if the P2 bit is accurate enough to actually fit an iPhone screw. I got a P2 bit for cheap on Amazon, and it was too distorted to fit.

  3. I would be scared to use a powered screwdriver regardless of the size or torque on some of the small electronics screws out there. If you strip them you’re screwed (groan!).

    The other issue with this is the chuck is very large – it’s OK for external screws but often time I’m digging deep into something and need a slender shaft to fit into the areas.

    1. Alan, what if the bit skips out off the screw head and you wind up engraving delicate circuitry with a spinning blade or Philips head? There is a reason we stop using powered screwdrivers after the initial case opening. That reason should also apply to the delicate finish of your iPhone.

  4. The more I think about it, I would ONLY use a motorized screwdriver like this for repetitive unscrewing where torque and unintentional damage is less of an issue. Otherwise, I always reach for my Wiha tools instead.
