“I bought these thinking I might use them. I have needed to connect straded cables, not solid core that works in the breadboards. These work great for that purpose! Hook one clip to the stranded core and then insert the pin and it works perfect. Would highly recommend these to anyone continplating getting them! Can also be usex to connect to a multi meter to make adjusents to a screw and get a reading at the same time! 100% worth the money!!”
