Oxford Chain Tool Pro

Worked perfectly. As others have said, it needs some grease first.

Feels like a well made tool, yet to actually use it yet though but I'm sure it'll do the job

I bought this tool after a bit of research to replace a #525 chain on my Tracer 900.
I was a bit nervous as I had never replaced a rivet link chain before, but I had noticed that my old one was coming apart as the end of the rivet link pin had snapped, so I was reluctant to try and ride it to a garage for replacement! After contacting the helpful staff at both Oxford Products and SBS for some further product info, I opted for this Oxford Pro tool from SBS as it is rated for up to #630 size chains.
I did not have to use the tool for removing a pin on the old chain as it was already coming apart, but if I did I would follow the recommendation to grind the head of the rivet pin first.
I found the side plate easy to press on with the Pro tool and checked it was pressed on the right mount by comparing it with other links using a set of digital Vernier Calipers. I was also able to flare the rivet pin ok with the Pro tool.
I would advise lubricating the tool with a bit of grease and using a socket wrench for pressing on the side plate and flaring the rivet pin, as it is easier than using the handle provided.
You can download a set of instructions for Oxford Products and it has a nice case to keep it all together.
In future I'll now be replacing all my bike chains using this tool!
