## Questions & Answers

**Q: Is it made of solid gold? Or alloyed gold? Trying to understand the $200 price for a sheet of plastic with two bits or metal tuning through.**
A: The description doesn’t say what the wire is made off, but I suspect it is copper and not just two strands of copper but multiple very thin strands laid side-by-side.  We bought ours nearly five years ago.  I think we paid $104 and I thought that was pretty expensive for an extension cord, but we needed it.  I am surprised at how much it has gone up in price. We are very satisfied with its performance thus far.

**Q: The plug in the picture looks like a us plug, why are people saying it doesn't fit us plugs?**
A: The problem is at the socket end -- this socket has two equally-sized slots.  Look at the plug on the device you're planning to plug into this extension; if it has a polarized plug (one blade larger than the other), it will not plug into this extension cord.  This is a safety issue and no company is likely to sell an adapter to bypasses this.  The only way to make this work with a polarized plug is to do some modifications either to the device you're plugging in or to this extension cord.

**Q: What is the total length from end to end (the flat part is 9.84 feet).  Can it be obtained in a total length of 11 or 12 feet?  My rug is 10.5 ft.**
A: 【Full length】 About 327 × width 8.7 × thickness 1.3 cm 【length of the flat part】 about 3 m × width 7.3 cm × thickness 0.9 mm 【weight】 about 390 g

**Q: do you currently sell the adaptor so that this product with work with American plugs?**
A: The one I bought had an american plug and did not require an adapter to work in the US.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great for under rugs
*by K***. on January 12, 2023*

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!

### ⭐⭐⭐⭐⭐ Great for electric couch
*by H***H on October 8, 2021*

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 bottomPolarized 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.

### ⭐⭐⭐⭐⭐ Perfect but pricy. You get what u pay 4
*by R***E on March 22, 2025*

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.
