I found it with a strap and not with a hook.
It measures accurately because I have compared it with another digital scale.
When the weighing is stabilized, it displays "hold" on the screen and the displayed value remains. Press ON/TARE to reset it and weigh again from the beginning.
You can also measure weight-tare. For tare, you weigh-zero and then add weight.
It operates with 2xAAA batteries (included in the package).
Dimensions: (L*W*H) 12*8*2.5cm

Negatives:
Reduced reliability due to cheap construction.
It requires caution not to drop it and the buttons are soft to press because at some point they may not respond.

I give it 5 stars in relation to its price of 6 euros.
