Review on 🔌 Glarks 300Pcs Open Barrel Wire Crimp Copper Ring Lugs Wire Crimp Terminal Connectors OT 5A 10A 20A 30A 40A 50A 60A 100A with Heat Shrink Tubing Assortment Kit for Auto Car Battery Cable Connector by John Swain

This set of open lugs and heat shrink tubing offers good value for money. I used the iwiss IWS-5100A open crimp tool, which I also bought from Amazon, to crimp the terminals on the cables/wires. The protrusions on these open cylinder ports didn't flex as much as I had hoped; They made a solid connection, but I would have liked the tabs to be fully bent in (wrapped) after crimping. I believe I used the appropriate terminals for the cables and wires and the crimping tool worked very well. Works to crimp terminals on cables / wires. It's just that the tabs on the terminals in the open case weren't folded over (twisted) all the way to get a tighter, stronger crimp. I really appreciated the heat shrink tubing that came with the clamps in this kit. I think the tubing was good quality and the shrinking on the connectors and cables/wires gave a very good seal/insulation. However, I don't know if I would buy this kit again because of the "short" open lugs. (I'm a hobbyist, though, and will probably never need to buy terminals again.) Again, this was good value, and the heat shrink tubing was a nice bonus.
