I'm just using this for hobby purposes at home but it works great. I've used some high grade power supplies so when I say this is a nice supply I have some experience. Now this is a low cost supply and I was concerned it might be a waste of money. So I connected a Tektronix scope to evaluate the output voltage. This is a linear power supply so the output voltage was very clean. I also checked for spikes when the output was switched on and off with and without a load and no spikes were seen. The current control and voltage control worked very well. The ability to connect this to your test circuit, setup the voltage and current and then turn the supply output on is a feature not even found on some high end supplies.
The only issue I had was the power cord connection on this supply seemed a little lose to me.
I would recommend this to the electrical/electronic hobbyist.

Solid Unit for the Money
According to Amazon I purchased this 10 years ago. I'm surprised they are still selling the same model. It's worked well for me. The current limit works as well as the voltage limit. The current limit can be adjusted in 1mA steps. The voltage limit can be adjusted in 10mV steps. I haven't noticed any appreciable spikes on activation of the output. The jog knob works well. The connections are solid. The on/off button is solid. The rubbery push buttons feel good enough. Once you get used to how the controls work it's relatively fast to adjust. I'm not seeing much noise either. It's actually quieter than any of my USB batteries that all seem to spit out some noise in the 450kHz range.
