Review on KNACRO Automatic Pressure Constant Stabilized by David Strawn

The first one I received was defective so I emailed the company and BOOM! They immediately sent another one along with a nice little gift for my efforts! Well done customer service. The person who contacted me responded quickly and as I said, they immediately resolved the issue to my complete satisfaction. This little board is the basis for my desktop power supply. I just added an inexpensive computer power supply that outputs 12V to power this board and the potentiometers on the board give me CV and/or CC. The voltage is adjustable from 0.8V to about 29V and the current ranges from about 300mA to much more than I need - so far it's sending out 3A with no problem. Thanks for a great product and even better customer service!
