"not bad if you use it as flat board not as electronic cycle board."
"As another reviewer does note, these are one-pad-per-hole boards, which means no hole is connected via a trace to another."
"Works great!"
"The board is pretty solid, the copper contacts are evenly placed and very easy to solder to."
"Hole size was smaller than I needed, should have been more observant."
"I have absolutely nothing negative to say about this perf board-- it works, which is probably the greatest compliment one can bestow upon perf board."
"Would have gotten 4 or 5 stars if they didn't put a damn sticker on the thing."

Reviews
"Works well with my LG fast charging block--yes, it -will-. fast charge my LG V20 without any problems!"
"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."

"I have run out of power in airports, meetings, my car only to find my cable will not charge my iPhone. So I bought 10 and gave them to my kids, replaced all of the cables in my cars, house, bags."
"8/7/2017 New update: after using it for more than 6 months (use it 5 days per week in office), the cable is still in good condition and still look like new. I have confident about this product because (Base on my pervious purchased syncwire product experiences): (1) High quality Material: strong enough to protect the cables and prevent broken.

"They came in a packet that acts as a cord winder that you can use to store and protect the cord in your briefcase, glove box etc."
"You can't go wrong ordering this charger and the owner of the shop sent me an email stating that if anything goes wrong with the charger, he will make it right."
"Other positive reviews and lifetime guaranteed is why I purchase previously and this time for myself."

"I purchased this Klein Non-Contract Dual Range Voltage detector based on the quality brand name and reviews here on Amazon. I took on a separate project and wired in a new Irrigation Controller in place of one that had a failed LED display."

"The only issue I can report is that it appears to have safety stops inside the hot and neutral slots. I don't think it's the fault of the product more a case of a safety mandate interfering with a product operation."
"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."

Reviews
"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."

Reviews
"I solved this by marking each unit with a black marker in large numerals. With a little less attention to styling, and more to functionality, the manufacturer could have easily solved this problem."
"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. Or, if you plug the Etekcity Outlet into the top wall outlet you may find it difficult to use the bottom wall outlet if you were to want to use the bottom outlet for something like a Vacuum Cleaner or any other appliance that has a large plug."
"Additionally beyond that, the remain 4 that were functional out of the first set have been cycling daily (via RPi) for about 4 months now."
