Quick Take

The Kaiweets ES20 Precision Screwdriver Set is an exceptional toolkit designed to meet the demands of intricate and precise tasks. With its comprehensive selection of 120 bits and valuable tools, this set caters to a wide range of electronic, mechanical, and DIY projects. The screwdriver’s solid build quality, ergonomic design, and magnetic tip ensure reliable performance and comfortable handling. Including a flexible extension shaft, magnetizer/demagnetizer, and other electronics-specific accessories enhances versatility. However, the velcro fabric storage case doesn’t hold all the electronics tools tightly, so the occasional tool falls out of place. You also can’t adjust the torque settings, as you can with other electric precision screwdrivers.

Build quality and design

The Kaiweets ES20 Precision Screwdriver Set impresses with its sturdy feel in hand. The screwdriver handle is made from high-quality aluminum alloy, providing durability and a comfortable grip.

One feature we’d welcome with the Kaiweets ES20 Precision Screwdriver Set is knurling on the handle, which would improve its ergonomics among the best precision screwdrivers.

The overall design of this precision electric screwdriver is otherwise well-thought-out, with the forward and reverse controls well-placed for comfortable operation. There is also a 360-degree LED flashlight that is activated by pressing a button next to the forward and reverse controls.

The magnetic tip securely holds the bits in place, preventing accidental drops and ensuring smooth operation.

The bits are crafted from CRV silver nickel, known for its strength and resistance to wear, ensuring longevity and reliability. But consider that other precision screwdriver sets include bits made from more durable metal.


The Kaiweets ES20 Precision Screwdriver Set comes neatly organized in a compact storage case. While the case is made of fabric, it is highly durable and thick enough to protect against impacts.

The case is designed to keep each bit and tool in its designated slot, preventing them from getting jumbled or lost. The bits take up the left two-thirds of the storage case and are nicely seated in rubber holders tightly integrated into the case.

The holders grasp the bits with the proper force, resulting in easy removal and little risk of bits falling out of place. The holder slots are labeled with corresponding sizes and types, making it easy to locate the required bit quickly.

But it’s likely the labels wear over time with heavy use. We repeatedly scratched some of the labels, and the labels didn’t take long to smudge or fade.

The other one-third of the case houses the screwdriver, various electronics tools, and a USB-C charging cable. The screwdriver is held tightly in place with a slot and elastic loop, but some other electronics tools aren’t as well thought out and fit loosely in each slot.

Contouring the slots to each tool’s shape or adding an elastic loop would better grasp each tool. While this is one gripe we have with the set, it’s an admittedly minor one that isn’t critical.

The compact size of the case allows for easy storage and portability. The storage case dimensions are 17” x 9.25” (l x w) when spread open and 5.5” x 9.25” x 1.5” (l x w x h) when closed.
