I replaced my Bell outlet box (which was beginning to rust badly) with this outlet box (see picture). This is a huge box for a single outlet -- it is a heavy duty box fabricated to withstand virtually any condition, for example, backing into it with your garden tractor (but no, I have not tried that). It is large and green in color, so it does stand out unless it is mounted among your plantings -- I installed it by my rear yard shed, so its aesthetic features did not concern me.
In addition to it's heavy duty design, I like the fact that the cover is NOT spring loaded, but will stay in an open (upright) position without slamming on your hands, At the same time, the cover is designed so that it can be moved to a downward, closed position even with cords plugged into it, providing protection from the weather (and curious little hands). The box is easy to mount, as it has several pre-drilled holes available to accommodate most mounting positions, and the cover has a hole that when aligned with the box in a closed position can be padlocked (see pictures). I was pleasantly surprised by the grounding lug built into the box (see picture), providing a secure means to attach your ground wire.
Were it not oversized for the job, I would have rated this 5-stars. My guess is that the manufacturer uses the same size box to sell many different outlet/electrical configurations. While a large box might be necessary for a more complex configuration (multiple outlets, switches, combinations), it is overkill for this one containing just a single GFI receptacle. If your mounting space is restricted, I suggest you check the dimensions before you purchase this.
Pros: Lots of Features, Nice Design, commercial grade
Cons: oversized box
