"Installing the outlets was easy, though we can only connect 2 wires to each side, not like standard outlets that can handle 3 wires."
"Easy to install assuming that you have a standard box."
"I installed three of these about 18 months ago and they have worked great."
"Our phones and tablets charge quickly with this outlet and it looks great."
"This uses most of the width of the box and there is no exposed wires except for the ground."
"That was the situation with one box on my island."
"This outlet is better suited at the end of an electrical run so you only have half the wires."

"The little leather straps with the buttons?"
"Excellent fast charging cable, very good price."
"I'm not really the kind of person who's attached at the hip to my phone, so I'm not really bothered by the extra time it takes to charge, especially for 20% of the price of the quick chargers. The packaging was also very good, and they both come with a little leather band with a snap to wrap up the cord when it's not being used."
"The nylon threaded cord is a nice touch and I don't feel like i'm going to damage it if I accidentally roll over it with my office chair. I have to wedge the cable so it remains still or hold the phone and cord together for there to be a charge. The strap although a good idea is a bit tricky and you have to thread it to the cables for it to actually close."
"Besides, I'm sure that due to my phones manufacturer since it was with any other charger cable to "Use charger that came with the phone" they just can't legally block other chargers so 3rd parties have to find a way for phones to read them as Quick Chargers."
"There's no sense in being careful to only buy 2.4A wall plugs if your cord can't deliver 2.4A to the device.There is a leather strap attached to each cord which makes these easy to wind up for travel or easy to wind up the excess if you don't need the entire 6.6 ft length."
"Nylon braided exterior helps keep them from kinking-up while in use, the connections on the USB Female end as well as on the USB C Male end are all very solid & in addition to meeting all applicable technical specs, it is a beautifully designed cable at a useful, but bot unmanageable length of 6 feet."

Find Best Price at Amazon"This particular battery is purchased as my girlfriend really wanted a battery that she could carry in her purse as well as a battery that wouldn't take up too much space in her purse. It comes with a 5200 mAh power which can charge your phone about 1.5 times before it needs to be charged. This battery comes with four bright indicator lights which allow it to tell you how much power your have left on the battery."
"The battery comes with a micro-USB *and* a lifetime replacement warranty, something that I haven't seen much for portable batteries. As you approach the end of the battery's life it kind of stops you from using the tail end of the last dot of battery, probably to protect the battery itself which is good."
"I have the larger one (10000 maH) but wanted a smaller one I could keep in my purse and also to have for when my kids are on their tablets and need some charging which seems to be easier than plugging the tablet into the wall (my kids always end up pulling it out by mistake when it's attached to the wall- this solves that issue.)."
"Having bought multiple portable charging batteries for cell phones since I either give them away or send them to my family overseas, I have become familiar with how these battery packs work. I tested it with an iPhone and a Samsung phone, charging both to a 100% and automatically cutting the power feed to the phone avoiding overcharging the phones and retaining charge in the battery pack."
"It has very smooth, rounded edges and feels really good in my hand. My only real issue is, again, just like the 10000 mAh charger, it made a high pitch whirring noise for the first five minutes of owning it. Update: the whining noise came back and now persists when charging the pack."

"These remote control outlets are fantastic! Even though these things work even better than expected, I'm knocking off one point for the two cons below (neither of which is a huge deal, just a little inconvenient): Cons: - These remote control outlets are just a little too big, so if the other plug you are trying to fit in a shared wall outlet is anything other than just a simple plug, it won't fit."
"Although it is possible that I received a different or updated model, I thought I should correct, or rebut, some of the misinformation that I read in other reviews. In another case, I had a three pronged plug that I was using in the spare outlet, which had to be relocated, as it would not fit after installing the remote switch. But, very easy to just add the remote switch into a short extension chord, and the problem is solved. After the Holidays, most of these units will be relocated to my basement workshop where they will be subject to much higher loads and more demanding use. I will use one on a dust collector (about 12 amps draw), one on a vacuum, and even one on a strobe light so my wife can summon me if she needs to, without me cutting my hand off if she yells at me to come to dinner. So now my wife just hits a button upstairs and my strobe light in the basement lets me know she needs me to come up!"
"When you plug your appliance into the Etekcity outlet, in this case a lamp, into the front of the Etekcity outlet, the Etekcity body will either cover the top wall outlet when plugged into the bottom of the wall outlet.
