For the price it's OK

A 4 there's really no reason to complain, the small vise works well on my watch Victorinox (which dates a little and that's why I try to change my battery myself).
When I think that my end was cheaper to make battery replacement via the jeweler, it was like 5 and equip itself to change the battery it is justified only in the long term or when you have too lazy to get around town.

Note that watches for men this vice may be a weakling poile, typically to open the screw back my watch it took me heartily shake this little vice and bite the yellow plastic tend to bend copiously.
If your watches are tight as tight, I advise you to find a vice with aluminum bite that should not watch too mark the box and have a much firmer hold.

Note that this small vise holds but experience shows it is safe to tighten the vise to turn into a real noose attached to a workbench.

I used this vise in conjunction with the "background Watch Tool Screwed" () which is also Hits_FR but I have the touch to make it very squared, one caliber.
