I bought this item for a portable PA rack I built.
Pros:
It is solidly made with a nice thick power cord. The metal mounting flanges are nice and sturdy. Each flange has three mounting holes, allowing a single bolt to be used at each side if desired. In my application, this was very convenient as I was mounting the item inside a rack case and it saved two screws. The unit is also very good value for money.
cons:
The power cord comes out of the side of the unit behind one of the mounting flanges. I found I had to bend it at quite a sharp radius to mount the unit. In my opinion it would have been better coming out of the rear of the unit. I personally don't like that it has a power switch, as this increases the number of things to check if the rack has no power. I appreciate that some people would use it as the main rack on/off switch however, so I have not marked it down for this.
