Review on DROK DR-US180076 DC Voltage Regulator: 6-40V to 0-32V, 5A Buck Converter for Constant Voltage Current Step Down, Power Supply: 24V 12V to 5V, Adjustable Output by Justin Garrett

Really well regulated power supply that can run on both constant voltage and constant current. It's an amazing feature set for such a small, inexpensive device. Pros: * 5 amps of power with heatsink only = noiseless * Running continuously for two months and not even getting hot * Very accurate and stable power output * Good enough current signal to drive a pump or DC motor. Cons: * Burnt out after two months of light use * Noisy switched output can't drive microcontrollers directly (but can power anything that has its own regulator, such as a Raspberry Pi). Instead I gave it 4 stars because it blew out after two months of use. In the end, there was a short circuit on the circuit board next to the microcontroller that controls the control loop. This means it could be a manufacturing defect rather than a design flaw. So 4 stars instead of below.
