Seriously flawed design

This appeared to be a perfect solution to a competition for outlet space. However, there were two major problems that rendered the device useless: (1) the outlets did not fit any plug we tried to insert into it. The USB ports worked fine, but we needed both the USB and electrical outlets. How is it possible to sell something like this where the plugs physically don't work?? (2) the protruding plastic knob on the back is probably there to keep the device balanced and secure, but when I plugged the device into my wall, the knob-thing was too long, making the whole thing tilt out of the wall plug awkwardly. It still worked, but this was definitely a flawed design. I see other good reviews and don't really know what to think. Maybe we got a dud. Whatever the reason, ours is frustratingly useless. Enough to motivate a rare online review saying... maybe find something else.

Re: Safety Precautions/Restrictions

Regarding the requirement that the device be installed "at LEAST 30 FEET (10 meters) or more of wire" between outlet and electrical box is due to this type of surge protector relying on the resistance of the added length of wiring to fulfil its surge protecting capability. (It's thirty dollars) Most likely the manufacturer would not honour its warranty if it was found that usage was not in compliance.

Just what I was looking for!

Now computer and phone can charge at once.

Worth buying a second time

Bought our first one a couple of years ago to clear up the clutter of chargers on the kitchen counter. Worked like a charm. Needed 3 ports to handle the multitude of phones that a busy family carries. But also needed the plugs for slow cookers and other counter top appliances. The first one has been fault free, so I just purchased a second one for our new trailer. Same reason, too many devices kicking around. But I expect in the trailer that I will really appreciate the surge protection as well. Campground power is notoriously lousy, so protecting your devices is always a good idea; this will cover our phones, tablets, computers, and TV set. Maybe a little more expensive than I was expecting, but the thing works, and that's all you can ask!

Safety Precautions/Restrictions

I think this product is worth a rating of 5 stars, but the reason I rated it with with 3 stars is the required safety precautions. The enclosed piece of paper in the box says: SAFETY PRECAUTION DO NOT install this device if there is NOT at LEAST 30 FEET (10 meters) or more of wire between the electrical outlet and electrical service panel. This precaution should be printed on the box instead of just enclosing it inside. I live in a condo and the distance between the service panel and the outlet is less than 20 feet. There's no explanation about this distance restriction. I don't know why this product was approved by UL or CSA. I'm going to return this item.

Good plug in with USB

Great product. Works great. The only con to this was the first time you want to use a plug in, it is very hard to insert the plug. I had to get my husband to do it for me. After that is was easier but not easy insert.

Does exactly what it is supposed to.

Does exactly what it is supposed to. Love the USB connectors! It frees up space for other plugs.
