I have such a device for some time, because the pins can not change and violence, it is critical. Once the cheap thing itself has broken down (composite plastic parts) but because it was made so cheap it could be exactly composed so quickly. So now it's a tip fals not everyone knows! Will rausgedrückt grooved pins ie on one side of the pin has been pressed a little wide because you have to really be careful if you want to push out on the wrong side, the entire pen is pressed with its widest point by the whole band. That does not by any device. So first look at which side of the pin is slightly more willing or where it looks a little "Rough". this is the page where you want to press on no account !!! On this side of the dowel pin to be pushed out, ie on the opposite side must be pushed in to the device! And as a "previous speakers" already said, a few mm rausdrücken to a gripper engages. I with my thing quite a few watches, 20-30 shortened and still with my 1st pushpin. Anger there was only if an older clock should be shortened, the pins had "seized" as the device turns on, but with caution and dexterity it works well. So always look first where the grooved pin is at its widest, not push in there, because the pin is to get out!
