Is this set enough for opening a phone or laptop?

Yes for most common fasteners. It covers Phillips down to PH0000, slotted, hex, Torx and socket bits, which handle the screws on phones, laptops and consoles. Very deep or recessed screws may need an extension shaft that is not listed.

What does the magnetizer do?

It magnetizes the bits so they hold screws while you position them. You can also use it to strengthen a bit that has lost magnetism over time.

How is the set organized?

The bits sit in a three-layer case with labeled slots, so each size has a fixed place. That makes it easy to spot a missing bit and keeps the kit portable.

Does the handle retract?

Yes. The rubber non-slip handle extends and retracts, which lets you shorten it for tight spaces or lengthen it for more leverage.

Are the bits standard size?

They are precision 4 mm-style bits made for this handle. They are not intended for full-size power drills or standard bit holders.

Who is this set not for?

Anyone doing heavy repairs on large furniture or appliances with big screws. The bits are small precision sizes, and the handle is manual, so bigger jobs need full-size tools.
