I spent hours looking up reviews on all there bergeon 5700 clones and can say that though I don't have a real 5700 this is a well built product with a metal base to make sure it doesn't tip over easily. I've used this to replace the battery in some of my friends and family watches and to undo the case base on other watch I service like my tag heuer. One important thing to note is you should always!!! use a plastic bag to protect you watch back. But on the whole if your on the fence and need to open up a watch case safely and have tried the trusted 8 ball. I would get this over a jaxa too in a heart beat as this gives you peace of mind that you can undo this and not slip damaging your precious watch.

A solid good quality machine with many extras

Used in my office as I work with Rolex watches and has been an absolute god send to remove those tough caseback that my handheld one can't do.
