Review on Oumers Bike Link Plier - 2 in 1 Chain Plier for Missing Link, Opener, Closer, and Remover - Compatible with All Speed Chains - Bicycle Chain Repair Tool by Deshaun Fisher

We should have listened to the reviews, despite what it says, this is only for opening and not closing links. Several reviewers have said this and I thought they were just using it incorrectly. I've tried everything and there's no way to open this thing wide enough to close a link in a normal thread. I ended up taking another reviewer's advice and using a dremel to sand down the bulge that is preventing it from opening too far. Now it works as both normally open and normally open!
