I have way too many power strips, including a few that clamp on to the edge of a table or shelf, but most are not made very well. To me it’s important that a power outlet like this hold on to the table or desk strong enough that I can plug a power cord in one-handed. This one understands that and not only clamps from the bottom but is designed like the letter C to apply pressure equally from the top and bottom. A rugged steel design assures that I can tighten the clamp to it can’t budge. I like that it has three outlets because I have it attached to the edge of a table in my kitchen area where I work on a lot of little projects, sometimes needing to plug two or three things in at the same time.WHICH EDGENormally this would be designed to clamp to the top edge of a desk and be fully exposed. But remember I’m using this on a table in my kitchen area, I don’t want an unsightly power outlet staring me in the face as I eat breakfast. The angle of the clamp is ideal for mounting to the frame of the table where the outlet sits completely out of sight but fully accessible to use at any time.THE USB PORTSI didn’t buy this for the USB ports, although they are very handy when I am testing something new I bought, these days such products rarely include a transformer so it’s nice not having to look for one. That being said I am reluctant to plug important devices like my thousand dollar smart phone or my equally expensive iPad. It’s just as easy using the proper transformer that is designed for such items. So I’m not putting a lot of weight in my review on those ports. They’re handy but as a convenience, that’s all.YES OR NOWhat sold me on this brand is that I could buy it with the length of cord I need and not have to bundle up any excess. For a table or desk mounted outlet all I need is three feet to reach the wall outlet. My only suggestion is it would have been nice if they used a right angle plug instead of a standard grounded one. That’s not a big deal, just a suggestion. Otherwise I like this a lot. It’s evident that they use quality materials and it’s well put together. And compared to others I’ve seen their price is very reasonable. I like it.
