Great, durable tool
This product made replacing my 520 chain on my Yamaha a breeze. It easily pushed out the pin (no grinding required) and broke the chain on the bike. I also had to size down the new chain which was super easy. Riveting the new chain was super simple using the instructions and I achieved a perfect mushroom rivet. (First time riveting). This tool is pricey but it is worth it for the peace of mind over buying the $20 one. Nothing bent or broke and everything went smoothly.

Durable and easy to use!
Worked great. Used it a few times now and it’s very durable and made out of great and strong materials. Very easy to use. Made the job so much faster and easier for me.

Works well enough
Replaced the factory chain on my 2023 Triumph Tiger 660 and needed a chain breaker/rivet tool. I didn't want to go cheap and this one seemed like a decent value compared to some other ones that I looked at. It popped out the original pin from the OEM chain without me having to do any cutting or grinding. The instructions were pretty good, although I did get a bit confused over using the tool to install the master link plate versus the actual riveting. Overall, I'd recommend this tool - seems well made and I didn't have any issues with anything bending, breaking, etc. I also followed the instructions and greased everything up prior to use.

Questionable QC and no warranty
Threads needed to be chased with a die before using due to poor manufacturing. Push pin broke on first use, tried to warranty the tool but they told me I need to buy replacement parts. Not worth the premium price tag.

DON’T MAKE MY MISTAKE
Product seems okay as described ONLY two notes 1. - It only came with one pushing pin so if that were to be bent you’d have to order another one. 2.- this was my personal issue and DON’T make my mistake. I order a “used” but in great condition one from amazon for -$10 less. Turned out to be one someone used, bent the push pin, then promptly returned thus making it unusable for me. Overall item seemed good but buy it new if your going to buy it or find a specific chain cutter/anvil for you 520,525,530 chain etc…

the real deal
if your tired of the bs chinese garbage chain breaker riveter sets that break and bend, do yourself a favor and throw that junk away... this is the minimum you want to spend.. the rivet breaker works perfect, and the riveter is set to the right depth so you cant over rivet the master link.. this is the real deal

Good instructions
Worked perfectly for first time use. Followed the YouTube video, and instructions and everything came out great. I was able to cut my last chain while being able to install a new one without any experience.
