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 Adam Vang

Working hence 3 stars. However, the breadboard is not a quality part. Difficult to insert any component, even the included cables. The board itself appears to be in three pieces (the power rails are separate pieces from the motherboard) that are held together with some sort of protective tape. My 30 year old Archer breadboard is much better. I haven't used the power supply for very long, but it supplied 3.3V with no problem. I'll learn more as I start mixing Arduino 5V and 3.3V sensors (with appropriate level shifters) and this power supply both have voltages to supply. The wires are ok but a bit long for breadboard use.
