Nice strip, wish it had a power on indicator
Color: Black, Size: 6FT Flat Plug
My first strip was DOA, and seemed to have been returned to Amazon. I say this because I was given a replacement and the packaging was different. First it was shrink wrapped, the first device I received was not. Second, the internal packaging was different. I scrapped my original review, and this review is based upon the working strip. This is an attractive power strip with 4 USB charger ports. I like the wall mount holes on both ends that provide a more secure means of attaching the strip to something. Most chargers simply have holes on the back to hang over a screw, this one you can actually fasten to something. The position of the outlets is good for clunky older power blocks provided they aren't too wide. They don't come close to interfering with the usb ports, ensuring you can easily plug in 4 usb cords and 4 power cords without having them get tangled up. My chief dislike are the lack of any power indicator. Almost every power strip I have owned in the last 30 years had some visible way to tell the strip was turned on. The other thing is the indicator to show which side of the power switch is on. The off side has a very visible white dot, which would probably make most people believe that was the "ON" position, it is actually the off position. The on position is marked by a raised black bar(or perhaps it is a 1) which is difficult to see. I think I would have just painted the traditional "on" icon next to the power on end of the switch. Again, a power indicator here would have made all the difference.

terrific, low cost power management tool
Color: Black, Size: 6FT Flat Plug, Color: Black, Size: 6FT Flat Plug
I noticed that most of the power outlets I use on a regular basis are behind large pieces of furniture. Every modern device requires at least a little power (even if only at intervals) and many of them have to be periodically unplugged to be rebooted. This invariably leads to a bulky power strip/surge protector at every usage location. Most power strip/surge protectors are very bulky and made to sit on the floor, often in a difficult location for routine access. Unfortunately, “unplugging” from a power strip requires holding the strip firmly in place while simultaneously pulling on the plug. With the strip in a difficult location and the fact that it must be restrained to remove the plug, I typically need a scotch to even attempt it. If that weren't bad enough, most devices use an AC adapter of various different sizes, shapes and orientations. The differences are odd enough that they look like a heterogeneous collection of "rugrats". This further magnifies the problem because power strips are never devised for the space requirements of rugrats. Most power strips assume that everything is a standard 2 or 3 prong plug, lined up in military fashion. So, to make a power strip work, it must often be combined with a variety of cube taps, shifting the vertical dimensions of many outlets to accommodate the different rat dimensions. In some cases, power strips start looking like tenement slums. Power strips that attempt to accommodate the dimensions of rugrats are even bulkier and more difficult to use. The overall problem was difficult enough that I recently decided to just sacrifice the furniture. This surge protector power strip has a very low profile with two screw slots at either end. There are locations on all outlet-blocking furniture where the strips can be screw-attached (see photo). This solves nearly all the problems: (a) the strip is convenient to someone seated in the chair or laying on the bed; (b) it’s strongly secured meaning the plugs can be easily removed and replaced with one hand; (c) it has one wide-spaced outlet for the odd rugrat; and (d) it has multiple USB ports with one ‘C’ type charging port, thus eliminating one rugrat. Given all that and that fact that it’s very reasonably priced, I couldn’t be happier.

Best Power strip to organize all your electronics.
Color: Black, Size: 6FT Rotating Plug, Color: Black, Size: 6FT Rotating Plug
The best extension cord I ever had so far, it's my 1st day using it but my life has changed for the better. I order yesterday they arrived today, very quick delivery. They were packaged nice and neat with instructions and screws if you want to mount. I love the Rotating Flat Plug, very nice and neat. My life is very busy and I need to be organized with 2 cell phone, laptop, smart watch and headphones. I was having to charge one or two at the time with plugs all over the place. Then having to take charger back in forth from my office to my bedroom and to work. Too much of a headache, I been looking all week and I needed 3 port c and 1 usb. Game changer for the best and I highly recommend to buy. I bought 2 and will be buying 2 more. I bought black to match my furniture. The best $20 I ever spent!!

Surge Protector
Color: Black, Size: 6FT Flat Plug
Without any conveniently located outlets nearby, the TROND Surge Protector Power Strip with USB allowed us to charge devices comfortably from the sofa. The 6-foot cord was perfect for our needs, and I appreciated the flat plug design. Purchased in 2017, one of the USB ports eventually failed, but the AC outlets still perform as they did when first purchased.
