Works great.  For a less-than-$4.00 tool this is excellent.  I removed links from 2 Citizen watches (male and female bands) that a jewelry store quoted a price of $12.00 each.  My wife is delighted, and that's what it's all about.  Especially since I bought them as an anniversary gift --- 57 years--- diamond in a few years.  Yikes !! Take your time and work SLOW and under good lighting.  Packaging and delivery was great !!
