Review on Kuman 830 MB-102 Tie Points Solderless Breadboard with 65pcs Jump Wires, 3.3V 5V Power Supply Module - Arduino K3 Compatible Electronic Learning Kit by Donnie King

in general: I would spend your money elsewhere if you are looking for quality. The board performs poorly because it doesn't hold the components very well, and if you find a port that sticks it might not even let power through. However, this device is very cheap and the power adapter is a decent value. The jumpers on the power supply are also of poor quality, which can lead to uneven current flow in projects. Pros: cheap, comes with a few jumpers, PSU is decent, actually works for a while. Cons: looks cheap, positive/negative number markings are easily erased after only 2 hours of brief use, connection with attached components is mediocre at best, resulting in a poor experience, adhesive backing peels off easily as if stored for a long time would be time. I would open it up to see if the terminals are all there or rusted but if my college needs the kits this week.
