SylsGate I’ve had Wowstick & also uses different kind of electric screwdriver but wowstick has a normal gearbox which easily break but es126 have a planetary gearbox which i found more durable and last longer. I used my wowstick for a few months only then the gearbox broke same as the other electric screwdriver, i’m using my es126 for almost three years now.

SylsGate A25 has a glow in the dark transparent body that glows brightly in the dark when exposed to a bright light while the A28 has a full transparent body but both has a glow in the dark inside the body holding the board and the battery, there is also a difference in the LED used for the UV light and i like the A28 uv light better.

SylsGate Yes wowstick bits are compatible and I am using the longer bits all the time because I also have the wowstick but the gears broke and it is more expensive thats why i bought this yunzhong and i liked it because it has more torque and speed than wowstick.

SylsGate Yes it is normal. It is a feature that protects the LED from burning.

Sylwin Yes it is the same
