Title: BAD SERVICE
Review: I purchased " Mastech Dual DC regulated Power Supply ". When I plugged the power cord in and turned the switch on, nothing happened. No light, no nothing. Then I tried to plug it in many different power oulet, it still did not turn on. So I called Kaito, and they told me to return it back. After waiting a few weeks and no feed back, I called them back to find out what is going on?. They said that they are about ship it back to me today. And also they told me that the reason the power supply will not turn on in the first place because they forgot to switch from 220 to 210 power system(made in china) before they ship it to customer. Their little mistake cost me time and money to return it back. Therefore I would not recommend this to other customers. This power supply looks like a toy. The knobs do not seems to be last long.
