A bit plasticky but will do.
D
Disappointing. i ordered and waited to open the back of my seiko watch. i had to use the smallest setting which should of gave the best chance at getting enough torque to open but it keeps moving. tried many times thought it was going to break because it seems a little flimsy but it just slips out. i see another one that uses three spots for a couple more dollars so let s see. if not off to the jewelers.

Works well.
K
Excellent

Kinda wobbly but does the job.
A
Good 👍
E
This tool works ok if the case back isn’t too tight, but not heavy duty enough to really wrench hard on a tight one. it just bends.
Z
I tested opening and closing a watch; the screw has some play and could be adjusted more precisely.
J
It seems built fairly well, but the two pins don’t come to the end of the slot at the same time. they both don’t close down all the way, or open up all the way.
V
Perfect, thank you.
E
Perfect.
