Review on Makeronics 840-Piece Jumper Wire Kit: Ideal for Breadboard Prototyping, Solder Circuits, Electronics Experiments, Arduino, Raspberry Pi, Jetson Nano - Includes 14 Lengths and Convenient Storage Box by Stephen Good

These are amazing jumpers for working with prototyping boards. The quality control is top notch, with quality curves at the end and otherwise nice straight pieces. The kit that includes them allows you to organize your parts well and the tweezers are of very high quality and include a protective case for the tips. They do NOT claim to be copper and are NOT copper; But the aluminum wires are the right gauge, strong core and shape, and fit right into all the different layouts I've tried them with.
