I have one. I really like it for storing my safety gear (goggles, knee pads, gloves, etc.)... The way it opens makes it not super ideal for constant opening and closing, which is why I use it for the safety gear. Not a lot of need to get at that stuff very often, after you get what you need. I imagine it would be good for electricians, though. Seems a good way to lug around stuff one might need for wiring, and what not. And having it opened up, while working, seems logical and quite handy, in that situation. All-in-all, Id say it's a bit of a niche item. But, very useful in the right situation. Pretty durable, in my experience.
