What is your opinion of this product?
I own and use four Hosa ACD477 wall warts. Every one has worked in every application I used it for, and not one has ever failed me. One has been running in a nonstop, high-drain application for four years without a complaint. These are quiet, they don't add him or buzz. With a 1200ma current output, they can power virtually any 3, 4.5, 6, 7.5, 9, or 12 volt DC device, with either a + or - ground. I had to write this review in response to the one written by the person who apparently received a broken one. I treat mine with respect, but if you rough-handle one, you could probably break it. But come on, it doesn't even cost $14.00! At that price, it's not going to be bullet-proof. In case you were wondering, I noticed the poor review as I was in the process of ordering another one of these great wall warts. My applications for these include: two large pedal boards, a high-powered boom box (the high-drain application I never shut down), a digital wireless system, a Boss ME-70 guitar multi effects processor, and a Zoom MS-60B bass multi effects processor (when # gets here).
