I had a small (700mA) phone charger on one of my Raspberry Pi's, and although wasn't having any problems, figured I'd try this, especially for the price. What can I say? It works fine for my purpose. Would purchase again.
I am very pleased with my experience with MCM. The website was easy to use, and has some very competitive prices. My order was shipped very quickly and I received my order less than a week after I placed it.
