Review on Comprehensive ELEGOO Electronics Component Pack: Arduino UNO, MEGA, Raspberry Pi Compatible with Resistors, LEDs, Switch, Potentiometer by Jimmie Trotto

So far the kit looks ok and all other components are checked ok but I had problems with 65 pcs sweaters! Most of them tend to have some kind of connection problem when you flip them and plug them into the Arduino breadboard. When preparing a test circuit, a bad jumper can be a nightmare. After several attempts to fix the circuit. I found that the jumpers from that kit were to blame. Attention electronics lovers! Jumpers included - junk. Must rate the kit three stars! EDIT: November 03, 2018 - Changed product rating to five stars! The manufacturer contacted me and accepted my feedback on the jumpers. The manufacturer has kindly replaced the faulty jumpers. This clearly shows that the manufacturer cares about the quality of their products and offers excellent customer service. Since the jumper replacement is awesome, I'm re-evaluating my rating to five stars!
