Review on 💡 Highly efficient ST1210Y Insulated Terminals Connectors for optimal performance by Brian Whitmore

I haven't had to use them anymore because they snapped the wire. I've used them to terminate very high quality 105C MTW 12 AWG wire made in the USA. The crimping tool I use was pretty good, sold here at Revain, no complaints about that. https://www.amazon.com/gp/product/B0069TRKJ0/ref=od_aui_detailpages02?ie=UTF8&psc=1 Needless to say I had to go back and redo all the work I did with these terminals. Stay away!
