the thinnest extension (power) cord in the world 0.003-Inch Flat Code 9.84-Feet Black

This extension cord is much flatter that the other "flat" cords available . It is undetectable under the rug I have. Only drawback is the unpolarized straight prong plug on the end. All the adapters I found for 2 to 3 prong were polarized, so one blade was thicker and it wouldn't go into the extension cord. Finally I realized I could use a travel adapter. The Japan 2 to 3 prong adapter fit and now the reclining couch works great and I don't have a raised area on the rug. The cord is expensive, but if the lump in the rug bothers you as much as it did me, it's worth it!

I bought this to run under a rug to power a couch with electric recliners/headrest/USB. It works perfectly for that purpose. No lumps under the rug, and to my surprise, the plug for our couch was non-grounded and non-polarized, so this worked for me without an adapter. Yes, this is expensive for an extension cord, but to power a 4 motor couch I realized we would need to buy a $300 battery + have the hassle of recharging it every few weeks. This ended up being a better and more economical solution. Grounded plug = a plug with a third prong on the bottom Polarized plug = two prongs where one side is slightly larger than the other. This extension cord is a “Type A” plug which means it accepts ONLY two-prong plugs and both prongs must be the same size (non polarized and non grounded). Check what you’re going to plug in to this as that will determine if you’ll need an adapter.

Phenominal. But I wish it was polarized, and I wish it had 3 prongs. But at least polarized. Thus the 4 stars instead of 1. But it's great! To address the polarization I used tape to mark which side matches to what.

I bought two of these to provide electricity underneath my rug for my lounge-set. It’s completely invisible and works like a dream. I cut off the plugs and replaced them with New Zealand plugs after pulling the cords through the carpet. Cons: expensive and the cable on the end is a bit short. Pros: robust solution which is completely invisible

Just as advertised. Flat. Fits American plugs, no converter needed for powered furniture. It comes rolled up but didn't need to use a hair dryer it will get even more flat with time. It's under a skinny rug , no pad yet and it's just what I wanted.

Had it in for about a week. Like most reviews mention no ground in the sockets, 2 prong only but female end is thin so ground prong slides right over the outside. Works good do far. Not noticeable at all under rug.

Female and male ends of pugs are not polorized like standard plugs. Would be helpful if this was in product description.

Runs under an expensive Turkish rug, you can't tell it's there... this thing is really thin, amazingly thin, like paper thin, the plug is a challenge tho, had to trim the extra "wings" off the polarized plug I was using it for... the female portion of the plug won't allow a polarized plug... so you just trim a little off and it fits... that was my only complaint... its a little bit of a challenge, but worth it.... if you have $150 to spare... I love it!
