Review on 🔧 Oumers Bike Chain Tool + Chain Checker: 2-in-1 Universal Bicycle Chain Repair Tool and Bike Chain Splitter Cutter Breaker with Chain Wear Indicator for 7, 8, 9, 10 Speed Chain Link Maintenance by Marlin Atonyo

I have used and broken several chain tools and chains in the past. This jig is adjustable at both ends to protect the chain and chain tool from bending, which is very useful. A metal clip on the chain tool holds the chain together, allowing you to adjust the links while pulling the derailleur. This helps a lot in fixing the chain on the fly, as happened to me on the road the other day. A voltage tester is a good thing to add.
